-- Information about the crash:
after browsing the folder hierarchie, I clicked with the right mouse button on a symlinked folder - dolphin crashed.
this i can reproduced anytime i want. 
I have also Insync 3.7.14.50440 installed, but the problem occurs also on not synced symlinced folders, so I am not sure that the application cause the troubles

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
