Sentry Crash Report:

Description Edward 2017-03-20 20:52:39 UTC

Application: amarok (2.8.0)
KDE Platform Version: 4.14.30
Qt Version: 4.8.6
Operating System: Linux 4.4.49-16-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
Querying MusicBrainz in order to update tags on Amy Winehouse's album "Lioness: Hidden Treasures".
Crash happens consistently for this album in particular, with the progress bar at about fifty percent. Does not happen with other albums.
My offhand guess: MusicBrainz is returning malformed data, and amarok is not catching the resulting error and handling it gracefully.

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