Summary: noatun crashes on exit or reconfiguration when multiple
"other plugins" are enabled
Product: noatun
Version: unspecified
Platform: Compiled Sources
OS/Version: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
AssignedTo: kde-multimedia@kde.org
ReportedBy: arhbaum@fas.harvard.edu
Version: (using KDE KDE 3.1.1)
Installed from: Compiled From Sources
Compiler: gcc 3.2.2
OS: Linux
My noatun often crashes (SIGSEGV) on exit when I have two or more "other plugins" \
enabled and am running a skinned interface (e.g. winskin, k-jofol, kaiman). Some \
combinations of "other plugins" that cause the crash are Young Hickory (YH) with Tag \
Reader (TR), YH with Keyz, and HTML Playlist Export with TR. (I had trouble \
reproducing it with YH and HTML Playlist Export.) However, it does not seem to crash \
if I select "quit" from the YH popup menu (as opposed to closing the open interface \
window).
It also crashes when I try to change from a skinned interface to an arbitrary \
interface with similar combinations of "other plugins" enabled. It also crashes if I \
am in the configuration window and I try to change too many of the plugins I have \
loaded (either interface or "other plugins") at the same time. For example, if I am \
running k-jofol, HTML Export, and TR, I can disable HTML Export and TR while enabling \
YH and Keyz and I get the following backtrace:

=====================================
Below is the backtrace I got when I initially identified the crash. I was running \
winskin, YH, and TR when I clicked the close button on the winskin interface and got \
a segfault on exit.

It seems like this might be a case of the "other plugins" interfering with each other \
and locking gears. I am using qt-3.1.1. \
