Description Milian Wolff 2011-02-12 20:02:57 UTC 
Application: kdevelop (4.2.60)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.31-19-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
I've switched between master and 1.2 branch of KDevplatform, and the session that had kdevplatform + kdevelop open crashed. Aleix, seems like this is still not properly fixed. Could it be that an import job was still running and that it cannot handle this?

The crash can be reproduced some of the time.

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

Comment 3 Milian Wolff 2011-03-03 20:38:39 UTC 
still happening to me, just switching branches in kdevelop is enough for me - does this work for you Aleix?
Comment 4 Aleix Pol 2011-03-03 21:26:56 UTC 
Yes, it works switching back an forth. I'll check on a different system today.

*sigh*
Comment 5 Milian Wolff 2011-03-03 21:55:07 UTC 
hm it is better that much I do have to say, it's not as bad as before. maybe even fixed all together? I was pretty sure that I was running the updated version before I updated it but did not trigger this bug since...

though do you notice that upon switching branches most folders are missing files? maybe it just takes ages for the changes to come into effect but that should be improved as well I think
Comment 6 Milian Wolff 2011-03-03 21:58:20 UTC 
nope, still crashing, just takes longer now ;-)
Comment 7 Aleix Pol 2011-03-03 22:34:26 UTC 
i'll take another look into it. i'm afraid it can take a little long since i don't have electricity today :/
Comment 8 Aleix Pol 2011-03-04 04:12:57 UTC 
Created attachment 57661 [details]
possible solution

Can you try this one and tell me if it helps? (if it does I'll properly fix)

Thank you
Comment 9 Milian Wolff 2011-04-02 00:47:35 UTC 
no, still crashing even with this patch:

Git commit 256ce230b3672c2d85f6c0a51440263cab786004 by Aleix Pol.
Committed on 05/05/2011 at 02:29.
Pushed by apol into branch '4.2'.

Simplify cmake reloading logic.
Add more assertions, should make it easier if there's anything crashing. I used kde-runtime to debug it and it didn't crash once after the changes.

CCBUG: 266161

Really seems to be fixed now - great work Aleix! I'll open a new bug when I notice something new.

New crash information added by DrKonqi

kdevelop (4.4.0) on KDE Platform 4.9.2 using Qt 4.8.3

- What I was doing when the application crashed:

changed one of the CMakeLists.txt file.

The Version 4.4 KDevelop seems to still have that problem
