Description Herr Schmidt 2017-01-14 03:08:02 UTC

Application: amarok (2.8.0)
KDE Platform Version: 4.14.26
Qt Version: 4.8.7
Operating System: Linux 4.8.0-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (stretch)

-- Information about the crash:
- Unusual behavior I noticed:

After I locked my screen and returned typing in my password instead of unlocking I get to the login screen. After login and automatic start of Amarok I get an error message:

Die Amarok-Datenbank berichtet die folgenden Fehler:
GREPME MySQLe query failed! (2000) mysql_embedded: Shutdown complete
 on init
In den meisten Fällen müssen diese Fehler behoben sein, bevor Amarok vollständig funktioniert.

And after trying to close I get this bug dialogue.


Additionally I get the following segmentation fault:
korgac PID: 9713 Signal: Segmentation fault (11) Datum: 14.01.17 03:38:56

The crash can be reproduced sometimes.

-- Backtrace:
Application: Amarok (amarok), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

There appears to be a packaging error in Debian for the MySQL part, please address this to your distribution.
FWIW: we didn't change anything in the code or the tarball, so that is very likely a downstream problem, and you are the second one to report this on Debian testing.
