-- Information about the crash:
- What I was doing when the application crashed:
Every time I switch git branch KDevelop crashes if the switch affects a CMake file in the project. It doesn't matter whether I make the change via KDevelop or separately in a shell. At least for one project this is reproducible every time.
I believe (though I'm unable to verify due to a lack of recent changes in the remote repository), this also happened at least once when I pulled updates from a remote repository. My suspicion is that this crash is related to changes in the cmake files, not to git.

The crash can be reproduced every time.

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