Sentry Crash Report:

Description Adam Lyall 2013-01-28 12:12:44 UTC 
Application: kdevelop (4.4.1)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-22-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
When I use Pick Session (either gui or commandline) to load an existing session, the application will crash once loaded. However, if I start a new session and from there pick an existing session from the home screen, Kdevelop will load that project just fine without crashing. I have noticed that when I use the later method KDevelop will usually do a full scan of the code (the update thing in the bottom right corner), where as with the former method that bit shoots to 100% (as it always did on a session resume) and then crash.

Note I was getting this all the time on my projects using pick sessions at first but sometimes it seems to start working just fine again after I have loaded a project session using the home screen on a new session.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted

Kdevelop just crashed again upon reloading a folder. I'm attaching that backtrace here in case it is relevant to this issue but if you think that is another bug I can create a separate report?
