Bug 309026

Application: kmenuedit (0.8)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-32-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:  Was moving an application from the "Lost and Found" to the "HamRadio" menu using the cut and paste optionsad previously moved "dictionary" from "lost and found" to "office".

The crash did not save either application --- they are both still in the "lost and found" folder.  These application where move up the system upgrade process when "kde-full" was added to ubuntu 12.04.1

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDE Menu Editor (kmenuedit), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
