Bug 301910

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

I created an icon manually for Aptana Studio 3, it was located in my Desktop folder (there was a plasma widget). I ran Apatana, it loaded fine. I right-clicked on the instance in the title bar and selected 'Show a launcher when not running'. Plasma crashed and this bug report wizard popped up.

Upon subsequent tries, however, it worked fine. I assume it has something to do with the fact that I made the icon for a custom app and it wasn't originally in the menu system, but that's just a guess.


- Custom settings of the application:

Just that it was a custom app that I created an icon for

The crash can be reproduced some of the time.

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