Application: dolphin (15.12.3)

Qt Version: 5.5.1
Operating System: Linux 4.10.0-40-generic x86_64
Distribution: Ubuntu 16.04.3 LTS

-- Information about the crash:
When I right click on a file or off a file, inside the Dolphin UI so that the menu pops up, if I then hover over the Activities tab, Dolphin immediately crashes every single time. I do not have any updates to download or install.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
