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

Installing new services.

To trigger  do :

Open dolphin.
Go to preferences > context menus > "Download New Services".
As soon as the services window opens close dolphin then close the services
window by hitting the "x" on the top right.

The crash can be reproduced every time.
