From kde-bugs-dist Wed Jan 06 01:16:46 2010 From: David Boosalis Date: Wed, 06 Jan 2010 01:16:46 +0000 To: kde-bugs-dist Subject: [Bug 221466] New: plasma-netbook fails to start from command line Message-Id: X-MARC-Message: https://marc.info/?l=kde-bugs-dist&m=126274065917227 https://bugs.kde.org/show_bug.cgi?id=221466 Summary: plasma-netbook fails to start from command line Product: plasma Version: unspecified Platform: Ubuntu Packages OS/Version: Linux Status: UNCONFIRMED Severity: crash Priority: NOR Component: plasma-netbook AssignedTo: notmart@gmail.com ReportedBy: david.boosalis@gmail.com Application: plasma-netbook (0.1) KDE Platform Version: 4.3.86 (KDE 4.3.86 (KDE 4.4 >= 20091231)) Qt Version: 4.6.0 Operating System: Linux 2.6.28-17-generic i686 Distribution: Ubuntu 9.04 -- Information about the crash: I use KDE from SVN and sometimes plasma-desktop crashes. So I start a konsole window with via f2 and try to launch plasma-netbook. It always results in a crash for which I hope the trace is attached in this bug report. If I start plasma-desktop it launches just fine. The crash can be reproduced every time. -- Backtrace: Application: Plasma Netbook (plasma-netbook), signal: Aborted [Current thread is 0 (LWP 7614)] Thread 3 (Thread 0xa6f1db90 (LWP 7618)): #0 0xb8065430 in __kernel_vsyscall () #1 0xb6ca20e5 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/tls/i686/cmov/libpthread.so.0 #2 0xb4c8ef3b in WTF::TCMalloc_PageHeap::scavengerThread () from /home/david/qt-copy/lib/libQtWebKit.so.4 #3 0xb4c8efc7 in WTF::TCMalloc_PageHeap::runScavengerThread () from /home/david/qt-copy/lib/libQtWebKit.so.4 #4 0xb6c9e4ff in start_thread () from /lib/tls/i686/cmov/libpthread.so.0 #5 0xb5db849e in clone () from /lib/tls/i686/cmov/libc.so.6 Thread 2 (Thread 0xa5ff9b90 (LWP 7619)): [KCrash Handler] #6 0xb8065430 in __kernel_vsyscall () #7 0xb5cff6d0 in raise () from /lib/tls/i686/cmov/libc.so.6 #8 0xb5d01098 in abort () from /lib/tls/i686/cmov/libc.so.6 #9 0xb6d23d22 in qt_message_output (msgType=QtFatalMsg, buf=0x95474f8 "ASSERT failure in QMutex::unlock(): \"A mutex must be unlocked in the same thread that locked it.\", file /home/david/qt/kde-qt/src/corelib/thread/qmutex.cpp, line 371") at /home/david/qt/kde-qt/src/corelib/global/qglobal.cpp:2226 #10 0xb6d23f63 in qt_message (msgType=QtFatalMsg, msg=0xb6ee12f0 "ASSERT failure in %s: \"%s\", file %s, line %d", ap=0xa5ff8fc4 "¤(î¶h(î¶\004(î¶s\001") at /home/david/qt/kde-qt/src/corelib/global/qglobal.cpp:2272 #11 0xb6d23fd1 in qFatal (msg=0xb6ee12f0 "ASSERT failure in %s: \"%s\", file %s, line %d") at /home/david/qt/kde-qt/src/corelib/global/qglobal.cpp:2455 #12 0xb6d2400f in qt_assert_x (where=0xb6ee28a4 "QMutex::unlock()", what=0xb6ee2868 "A mutex must be unlocked in the same thread that locked it.", file=0xb6ee2804 "/home/david/qt/kde-qt/src/corelib/thread/qmutex.cpp", line=371) at /home/david/qt/kde-qt/src/corelib/global/qglobal.cpp:1997 #13 0xb6d284b4 in QMutex::unlock (this=0x95529dc) at /home/david/qt/kde-qt/src/corelib/thread/qmutex.cpp:371 #14 0xb6d30a63 in QWaitCondition::wait (this=0x95529e0, mutex=0x95529dc, time=4294967295) at /home/david/qt/kde-qt/src/corelib/thread/qwaitcondition_unix.cpp:157 #15 0xa6076740 in WiFiScan::run () from /home/david/kde/lib/kde4/plasma-geolocation-wifi.so #16 0xb6d304d6 in QThreadPrivate::start (arg=0x95529d0) at /home/david/qt/kde-qt/src/corelib/thread/qthread_unix.cpp:244 #17 0xb6c9e4ff in start_thread () from /lib/tls/i686/cmov/libpthread.so.0 #18 0xb5db849e in clone () from /lib/tls/i686/cmov/libc.so.6 Thread 1 (Thread 0xb26d9720 (LWP 7614)): #0 0xb8065430 in __kernel_vsyscall () #1 0xb6ca4cf9 in __lll_lock_wait () from /lib/tls/i686/cmov/libpthread.so.0 #2 0xb6ca0129 in _L_lock_89 () from /lib/tls/i686/cmov/libpthread.so.0 #3 0xb6c9fa32 in pthread_mutex_lock () from /lib/tls/i686/cmov/libpthread.so.0 #4 0xb6d30b62 in QWaitCondition::wakeOne (this=0x95529e0) at /home/david/qt/kde-qt/src/corelib/thread/qwaitcondition_unix.cpp:132 #5 0xa60747f4 in WiFiScan::~WiFiScan () from /home/david/kde/lib/kde4/plasma-geolocation-wifi.so #6 0xa6074ec0 in WiFi::~WiFi () from /home/david/kde/lib/kde4/plasma-geolocation-wifi.so #7 0xa6083be6 in Geolocation::~Geolocation () from /home/david/kde/lib/kde4/plasma_engine_geolocation.so #8 0xb7c8853f in Plasma::DataEngineManager::~DataEngineManager () from /home/david/kde/lib/libplasma.so.3 #9 0xb7c886ea in Plasma::._183::destroy () from /home/david/kde/lib/libplasma.so.3 #10 0xb7c428cb in KCleanUpGlobalStatic::~KCleanUpGlobalStatic () from /home/david/kde/lib/libplasma.so.3 #11 0xb5d02bb9 in exit () from /lib/tls/i686/cmov/libc.so.6 #12 0xb61908a5 in qt_xio_errhandler () at /home/david/qt/kde-qt/src/gui/kernel/qapplication_x11.cpp:734 #13 0xb74737ba in KApplication::xioErrhandler () from /home/david/kde/lib/libkdeui.so.5 #14 0xb74737f6 in kde_xio_errhandler () from /home/david/kde/lib/libkdeui.so.5 #15 0xb7f4ff22 in _XIOError () from /usr/lib/libX11.so.6 #16 0xb7f57743 in ??
