Bug 176509

Version:           1.0.5 (using KDE 4.1.3)
Compiler:          gcc version 4.3.2 20081105 (Red Hat 4.3.2-7) (GCC)  
OS:                Linux
Installed from:    Fedora RPMs

A Fatal Error Occurred
The application unknown (k3b) crashed and caused the signal 11 (SIGSEGV).

Steps to reproduce: launch k3b from the kicker menu, wait for the splash screen to disappear and for the timed "No problems found in system configuration." message to go away, then exit k3b:  the crash happens by choosing File/Quit from the menu, or by closing the window from the standard control at the top right corner (either way).

The backtraces mention libselinux.so.1 which is temporarily disabled in /etc/selinux/config:
#SELINUX=enforcing
SELINUX=disabled
SELINUXTYPE=targeted

System config:
Fedora: 10 (final)
kernel: 2.6.27.5-117.fc10.x86_64
KDE: 4.1.3
k3b: 1.0.5
libselinux-2.0.73-1.fc10.src.rpm
