Description Germano Massullo (Thetra) 2017-08-31 07:47:33 UTC

Comment 1 Germano Massullo (Thetra) 2017-08-31 07:53:03 UTC 
In case you may want to investigate, the amarok bugreport is https://bugs.kde.org/show_bug.cgi?id=384211
Comment 2 Julian Steinmann 2018-06-08 15:48:15 UTC 
Have you experienced this crash again? The Amarok bug report is probably related to gstreamer but gstreamer does not appear in this backtrace...
Comment 3 Germano Massullo (Thetra) 2018-06-08 16:03:17 UTC

I have no longer experienced the problem recently
Comment 4 Christoph Feck 2018-06-20 23:39:13 UTC 
Thanks for the update; let's close this.
