Bug#40464: crashes when saving files

[jg.its at cbs.dk]

Package: kdevelop
Version: 2.1 (using KDE 3.0.0 )
Severity: normal
Installed from:    Red Hat Linux 7.2.92
Compiler:          gcc version 2.96 20000731 (Red Hat Linux 7.2 2.96-109)
OS:                Linux (i686) release 2.4.18
OS/Compiler notes: 

Whenever I'm trying to save files kdevelop dies. It does not actually crash since the KDE crash handler does not appear, unless when I start kde using gdb, then I get "unable to create backtrace" in the crash handler.
This is what I get when usin gdb:
