Please make sure you always use the very latest git build, current is at v2.7.0-299-g00eb2e4 1368975 2 79899 martin.ruessler 2013-05-15 11:46:38 +0000 Created attachment 79899 New crash information added by DrKonqi amarok (2.7-git) on KDE Platform 4.10.3 using Qt 4.8.4 Yes it seems that I can reproduce the bug. I went to the settings and started a full rescan of my library. After a while Amarok crashed.

I'll have a look at this later. 1379592 11 matej 2013-06-26 17:48:49 +0000 Git commit acf7cfabe5e51cef2704d76a4312724ebf4abfcf by Matěj Laitl. Committed on 26/06/2013 at 16:49. Pushed by laitl into branch 'master'. ScanManagers, ScanResultProcessors: don't call non-thread-safe code from a thread Excessive usage of direct Qt connections lead to a large amount of code in various ScanResultProcessors being called from a non-main thread, but the result processors didn't expected it, weren't thread-safe, which lead to data races. This fixes one confirmed crash and may fix more seemingly random Local Collection updating behaviour.
