Bug 227594

Application: konsole (2.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-174.2.19.fc12.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
Went through konsole's set up to change the default keybindings for the xterm selection ( Linux and solaris also have the problem).  Removing an existing keybinding causes segfault. Adding a keybinding and then trying to remove also segfaults. 

Note Using the fedora-kde testing repository.

The crash can be reproduced every time.

 -- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
