Bug 369421

Application: kmenuedit (5.7.5)
 (Compiled from sources)
Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.6.4-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:
I have cut a custom folder inside the "Development" category. A message popped up, saying that i cant cut complete directories and that i can . After this I pastet the custom folter into itself and deleted the pasted folder afterwards. Finaly i copied a real entry and clicked the custom folder to paste it in there. While clicking on the custom folder the editor crashed.

-- Backtrace:
Application: KDE Menu Editor (kmenuedit), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
