Application: dolphin (15.12.3)

Qt Version: 5.5.1
Operating System: Linux 4.1.31-30-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: I was using the Dolphin Addon Installer in Dolphin Preferences to add Menu Items. This occurred when installing kde-service-menu-aptk addon. It also crashed just a bit earlier whe trying to install a VLC menu addon also. Normally Dolphin is stable and not prone to problems.

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