Could be related to bug 222380
Comment 2 Mark Kretschmann 2010-01-26 20:33:01 UTC 
This looks valid to me (real Amarok bug). Confirming the report.
Comment 3 langstr 2010-03-06 12:47:48 UTC 
This crash is highly related to BUG 229240.

It involves 'PrettyListView' (findNext), it involves a 'QModelIndex', the code does a 'setCurrentIndex()' call just before the crash...

As I said in that other bug: I am not at all familiar with this code.

But it looks that the "setCurrentIndex()" calls in PrettyListView need a little wrapper function that creates a fresh and non-reused QModelIndex copy.

I will make a MR.

PS. I can not reproduce this crash myself, based on the information given by the submitter.

RoDrIgO, I have created a patch, but I can't test whether it fixes your bug.

Can you give a detailed step-by-step procedure to reproduce it?

Sorry, but since I've upgraded to a newer version of amarok, the problem solved. 
But I'm remembered I was making a playlist (queuing musics) and resolved to rating it at same time. 

Thank for helping

Good to hear that your problem already went away.

Your crash log was still very useful in confirming that other bug.
Comment 7 Myriam Schweingruber 2010-03-06 18:09:27 UTC 
Nanno, can I close this one?
Comment 8 langstr 2010-03-06 20:28:48 UTC 
My MR has not been merged yet. But neither the submitter nor me can reproduce it in current Amarok, so I think it is OK to close this for now.
Comment 9 Myriam Schweingruber 2010-03-06 20:41:08 UTC 
Closing then, thanks for the feedback.
