Bug 335761

Application: plasma-desktop (4.11.9)
KDE Platform Version: 4.13.1
Qt Version: 4.8.6
Operating System: Linux 3.12.4-pf-0s x86_64
Distribution: Ubuntu 14.04 LTS

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

Click on the upper left arrow on a folder on Plasma-Desktop to see the contents of it.	
Right click on a random file in the folder.
Choose "Open with"-> "Other".
Either I choose a specific program to open the file or Cancel the procedure,Plasma-Desktop crashes and restarts.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
