Bug 357892

Application: dolphin (15.12.0)

Qt Version: 5.5.1
Operating System: Linux 4.1.13-5-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
When right-clicking any file or folder and moving the mouse pointer to the "Activities" context menu dolphin always crashes (the window just closes abruptly without any error messages etc.).

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
