Bug 324146

Application: kdevelop (4.5.1)
KDE Platform Version: 4.10.5 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.8.13-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:

I was editing a program and accidentally hit Ctrl-Shift-Up while attempting to change workspaces (I meant to hit Ctrl-Alt-Right).

The editor page flashed briefly, I couldn't see what it was doing, then it disappeared as it crashed.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
