Bug 228899

Application: krunner (0.1)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-174.2.22.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
Fedora12 with kde-4.4.0 ant qt-4.6.2

Input the string "xscreensaver-command -exit" and pressed "return" and krunner segv'ed

Note that krunner has inexplicable waits on my system - even with nepomuk enabled (no strigi though)

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Run Command Interface (krunner), signal: Segmentation fault
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
