                OS: Linux

Application: kmenuedit (5.2.0)

Qt Version: 5.4.0
Operating System: Linux 3.16.0-31-generic x86_64
Distribution: Ubuntu 14.10

-- Information about the crash:
Kmenuedit crashed when I attempted to start it after the cache folder had been
cleaned of KDE related files to fix the SVG cache bug. There have been multiple
attempts to open it with the same results.

The crash can be reproduced every time.
