Sentry Crash Report:

Description optiluca@gmail.com 2009-12-30 17:35:01 UTC 
Version:           2.2.1 (using KDE 4.3.4)
Compiler:          4.4.2 CFLAGS="-march=native -O2 -pipe -ggdb"
OS:                Linux
Installed from:    Gentoo Packages

Whenever I create a custom playlist with x% "last.fm match song" and 100-x % "echo nest match song", amarok eventually crashes while playing tracks in the playlist.  This crash could be unrelated, but I have only observed it in this usage scenario.  Skipping tracks rapidly seems to make the program crash earlier, but eventually the crash occurs anyway.

Here is a backtrace (if it is useless then pls just tell me what packages I need to enable debugging for and I shall post a new one :) )

Comment 1 Leo Franchi 2009-12-30 17:38:47 UTC 
Hi, please try updating to 2.2.2-beta1, there's a good possibility that there was a fix for this in trunk recently.
Comment 2 optiluca@gmail.com 2009-12-31 00:48:33 UTC 
Crash still occurs I'm afraid.  However a backtrace isn't generated for some reason.  This is all I get:

Application: Amarok (amarok), signal: Segmentation fault
Comment 3 Leo Franchi 2009-12-31 02:00:12 UTC 
hmm, could you try this?

(first, install any amarok debug packages)

gdb amarok
<wait for prompt>
run --nofork --nocrashhandler
<amarok should open, do what you have to to make it crash>
<should be back to a prompt when amarok crashes>
bt

and paste the resulting backtrack

I got this by setting up a playlist with custom bias and keeping "del" pressed so as to make amarok continuously update the playlist, eventually it crashed.
Comment 5 Leo Franchi 2009-12-31 17:38:52 UTC 
ah,  thanks for the backtrace. you are running into a Qt bug in 4.6.0, which i *believe* is already fixed in 4.6.1 (the bug is in the qt image loading, when amarok tries to load some particular images as cover art).
Comment 6 optiluca@gmail.com 2010-01-02 12:10:32 UTC 
Got yet another crash today under different circumstances, same bug?  This time the kde crash handler has something to offer...
