Application: amarok (2.8.0)
KDE Platform Version: 4.14.13
Qt Version: 4.8.7
Operating System: Linux 4.2.0-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (stretch)

-- Information about the crash:
- What I was doing when the application crashed:
Tried to query tags via right clicking on a file → "Edit Track Details" → "Get Tags from MusicBrainz". While loading and having retrieved a couple of suggestions already Amarok suddenly crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
