Description Mark Kretschmann 2013-06-18 20:03:24 UTC 
I had a script called "Free Music Charts" installed and enabled. As I wanted to disable the script in the settings dialog, Amarok crashed when I pressed Apply.

Here's the backtrace:

Application: Amarok (amarok), signal: Segmentation fault

Reproducible: Always
Comment 1 Mark Kretschmann 2013-06-20 09:25:20 UTC 
I should note that the script was showing an error notification in Amarok on that day. The error had to do with being unable to access its web service.

My guess is that the bug gets triggered when no collection data was populated by a script.
Comment 2 Anmol Ahuja 2013-06-21 13:24:32 UTC 
Git commit f21c1bdbc325edeb36e4160fd23747c774179700 by Anmol Ahuja.
Committed on 21/06/2013 at 13:22.
Pushed by anmolahuja into branch 'master'.

Destroy ScriptableServiceQueryMaker if parent collection destroyed.
Set servicePtr to null on destruction, check for null in related methods.
