Description zohn.joidberg 2012-07-15 09:57:17 UTC 
Application: kdevelop (4.3.1)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-26-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I switched to another commit of my git branch.
Kdevelop had the corresponding project open and was using the project's cmake file.

The branch I switched too also had a CMakeLists.txt.

[Since this is a public git repository, I can even tell you exactly which commits :) :
Repository: https://bitbucket.org/Knitter/puzzlemoppet
I was at commit 32bec2e9c5dee804cdf0cc15f4ab16a54b4fc4c9 and did:
$ git checkout 02592bcc3792e085e3b26e9734197a73a0b2244c

New crash information added by DrKonqi

kdevelop (4.4.60) on KDE Platform 4.8.3 (4.8.3) using Qt 4.8.2

- What I was doing when the application crashed:
Changed files (incl. CMakeLists.txt) of a project currently opened using KDevelop.

The assertion text in .xsession-errors is:
*** glibc detected *** kdevelop: double free or corruption (fasttop): 0x00007f4d69dfd580 ***

- Versions
kdevplatform: v1.3.1-272-g569aa69
kdevelop: v4.3.1-262-g5f9644a

I have a Qt build with debugging assertions enabled, dunno if it is necessary to reproduce.

-- Backtrace (Reduced):
