[Pkg-kde-extras] Bug#1051462: kdiff3: segfault when quitting the application

[Ritesh Raj Sarraf]

Package: kdiff3
Version: 1.10.5-1
Severity: important
X-Debbugs-Cc: rrs at debian.org

Dear Maintainer,


kdiff3, version 1.10.5-1, keeps persistently crashing upon exit. I'm not
sure if the gathered trace is any useful but adding it here.

```


Reverting back to version 1.10.4-1 from snapshots.d.o is working
perfect. Thus I concluded that the issue is in particular with the
latest 1.10.5 version.
