Sentry Crash Report:

Description Davide Gianforte 2018-03-11 08:51:07 UTC 
Application: amarok (2.9.0)
 (Compiled from sources)
Qt Version: 5.9.4
Frameworks Version: 5.44.0
Operating System: Linux 4.16.0-rc3+ x86_64
Distribution (Platform): Slackware Packages

-- Information about the crash:
I closed Amarok with a USB mounted and some files from the pendrive in the playlist.

After the computer restart, Amarok crashes and when I restart manually, it shows ane empty Music Collection (from another directory on the HDD).

When I Update the Collection I get:

MySQLe query failed! (1194) Table 'devices' is marked as crashed and should be repaired on SELECT lastmountpoint FROM devices WHERE id = 7

and with 'amarok --debug' I get:

amarok:   [ERROR__] [MySqlStorage] "MySQLe query failed! (1194) Table 'devices' is marked as crashed and should be repaired on SELECT lastmountpoint FROM devices WHERE id = 7"
amarok:   [WARNING] [MountPointManager] Device  7  not in database, this should never happen!

many times. Amarok DB is not external. I have to find out how to read the 'devices' table or toggle the crash status.

If needed, I can switch Amarok DB to my local SQL database.

The crash can be reproduced every time.

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

Unfortunately you do not have debugging symbols installed. We would need a better backtrace, see also https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
