Application: kdevelop (4.2.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
I'm working on an embedded project with a cross compiler, so I have a certain gdb to use:
GNU gdb (Sourcery G++ Lite 4.3-51) 6.8.50.20080821-cvs

When I tried to start debugging, kdevelop tells me the version is tool old (not >= 7.0) and that it can't open a tty or ptty. Then it crashes. This is easily reproducible for me.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
