Bug 382875

Application: kdevelop (5.1.1)
 (Compiled from sources)
Qt Version: 5.8.0
Frameworks Version: 5.35.0
Operating System: Linux 4.9.30-ck1-mainline-core2-rjvb x86_64
Distribution: Ubuntu 14.04.5 LTS

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

I quit KDevelop after committing changes to a git project. I waited for the patch review view to be replaced with the regular coding view but apparently git isn't necessarily done at that point.

Terminal output:
kdevplatform.vcs: Found an error while running "git commit -m 'port:q4wine : initial working implementation (Linux)' -- /opt/local/site-ports/devel/q4wine/files/patch-use-our-rpath.diff /opt/local/site-ports/devel/q4wine/Portfile" : "Crashed" Exit code is: 15
kdevplatform.vcs: Error: "Process 'git commit -m 'port:q4wine : initial working implementation (Linux)' -- /opt/local/site-ports/devel/q4wine/files/patch-use-our-rpath.diff /opt/local/site-ports/devel/q4wine/Portfile' exited with status 15\n\"\"\n\"\""

QProcess: Destroyed while process ("git") is still running.
KCrash: Application 'kdevelop' crashing...

~VCSCommitDiffPatchSource() and ~VCSDiffPatchSource() had been called at this point.

Cf. #344710: same crash provoked in a different way.
