Description Jörn Schönyan 2014-04-21 11:02:26 UTC 
Application: amarok (2.8.0)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
A friend of mine is hobbyist dj and used my notebook so we could listen to music. Amarok crashed sometimes, about 1 time per hour. His music library is really large, more than 100.000 songs. This problem also existed in Kubuntu 13.10.

The crash can be reproduced sometimes.

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

Comment 1 Myriam Schweingruber 2014-04-21 20:06:54 UTC 
What exactly did you do when the crash happened? We can test with large collections, I can't reproduce this here at all with a collection of about 60'000 titles
Comment 2 Jörn Schönyan 2014-04-22 10:03:22 UTC 
Hello Myriam, hope you had a nice easter weekend :-)

Well, of roundabout 10+ crashes that day (we played music ~16 hours), I personally just saw one or two. My buddy told me, it happened while just searching. After reopening Amarok, searching again worked fine, even with the same keywords. Anything else I could help with?
Comment 3 Myriam Schweingruber 2014-04-22 10:25:00 UTC 
Thank you, Jörn, it was nice, hope it also was for you :)

Where is the collection located? if it is not local but on a remote share that might be the problem, as the connection can time out, but it should be possible to handle this on the system level to avoid time-outs.
Comment 4 Jörn Schönyan 2014-04-22 10:30:05 UTC 
Oh forgot to mention that, it was on an external HDD (USB3).
Comment 5 Myriam Schweingruber 2014-04-22 11:56:34 UTC 
Then it could be related to when the HD spins down, I had that quite often with an USB disk. But it shouldn't crash, instead provide an error message.

Thanks a lot for the fast feedback!
Comment 6 Justin Zobel 2020-12-14 01:31:03 UTC
