           Summary: kwin crash while trying to run qt-only program
           Product: kwin
           Version: 3.0
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kwin kde org
        ReportedBy: mw_triad users sourceforge net


Version:           3.0 (using Devel)
Installed from:    Compiled sources
Compiler:          gcc 4.1.2 
OS:                Linux

kwin crashed with the following backtrace. I don't know anything obvious to point to \
as a possible cause, except that I was trying to run a qt-only program (transtest.cpp \
from bug 157850 in fact, attachment 23870) and said program seems to be failing to \
produce a window at the moment.

Application: KWin (kwin), signal SIGSEGV
Using host libthread_db library "/lib/tls/libthread_db.so.1".
