Bug 336636

Application: plasma-desktop (4.13.0)
KDE Platform Version: 4.13.1
Qt Version: 4.8.6
Operating System: Linux 3.13.0-29-generic i686
Distribution: Netrunner 14 (Frontier)

-- Information about the crash:
- What I was doing when the application crashed: I had enabled  "delete" in Dolphin Services configuration. This allows you to delete a file from the service menu instead of just sending it to trash. The setting applies to the Folder View desktop containment also. When I delete a file on Folder View in this way. ie delete from service menu, it works fine. 

However, if I click the up-arrow overlay on a folder icon on Folder View so that the folder contents are displayed in a pop-up, then I right-click a file and choose "delete" from the service menu, Plasma crashes. This is reproducable, happening about 50% of the time when I do this delete. When it happens, the file is not actually deleted.

The crash can be reproduced every time.

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