Bug 243789

Application: kdevelop (4.0.60)
KDE Platform Version: 4.4.4 (KDE 4.4.4) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.14-127.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
I had auto-bracket extension enabled.  I disabled it in the Editor->Configure dialog; when I pressed OK, got the crash.  Tried opening a new project + empty file so there would be no parsing after the change, but still got the crash.  Happens every time.

The crash can be reproduced every time.

 -- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
