Bug 230147

Application: kwrite (4.4.00 (KDE 4.4.0))
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.9-67.fc12.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I was editing a file over fish://. Kwrite crashed when I closed kwrite.

This happenes occasionally, but I don't have a reliable way of reproducing the crash.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: KWrite (kwrite), signal: Segmentation fault
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
