Description Pieter Botha 2010-06-06 20:05:39 UTC 
Application: amarok (2.3.1)
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-0.2-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

-- Information about the crash:
What I was doing:
Playing an mp3 using a custom (copy from verbose with title only) playlist view
I then switched on APG
I then started editting the APG that was being played and added & removed groups.
At last I added a "added within the last X to collection" tag to a group and moved the fuzzy bar


The crash can be reproduced some of the time.

 -- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault

Confirmed by duplicate.
Comment 3 Soren Harward 2010-08-10 00:52:54 UTC 
This one is unlikely to get fixed in 2.3.2.  It's a KSharedPtr and Qt bug, not an Amarok bug (look at thread 12), and I doubt I'll have it tracked down and fixed by then.  It may not even be fixable within Amarok.

Comment 5 Soren Harward 2010-08-10 01:00:48 UTC 
Those of you who reported this bug or one of its duplicates, I need to know *EXACTLY* what version of Qt *AND* kdelibs you are using, or were using when this crash happened.  Since the problem is in Qt and/or kdelibs, I cannot start tracking it down without this information.

Git commit 98b561e2b738b55e3b9d94b4e6c6cd28f73261c6 by Soren Harward.
Committed on 30/09/2011 at 17:24.

Overhaul of Automated Playlist Generator algorithm

Completely rewrote the ConstraintSolver to use a genetic algorithm
rather than simulated annealing.  This trades off some speed for a vast
reduction in the amount of code needed to write individual constraints,
and makes the whole component less prone to crashing.
