Application: kdevelop (4.3.1)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-32-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
Whenever I try to debug a conosle app using the external console feature, KDevelop crashes and/or complains about /dev/tty permissions.  /dev/tty permissions are fine, I suspect this is something else.  This problem has existed for a long time at least in ubuntu and debian.  It crashes with both konsole and gnome-terminal.

The crash can be reproduced every time.

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