Confirming this bug on an up-to-date Sid Debian (PPC64) with the 2.2.0-1 version of Amarok.

It does not look like 209649 has anything in common with this bug, it
has a completely different backtrace. Are you sure that you selected
the right bug?

I cannot reproduce this crash any more with the latest 2.2-GIT code. I did extensive testing with the Icecast Directory script, there was not a single crash.

I assume it has been fixed.

I take that back. It has just crashed on me:

I think I've fixed it now:


commit f565187a1e81e28304d71304b7593b3d0d2ae6e9
Author: Mark Kretschmann <kretschmann@kde.org>
Date:   Mon Nov 2 12:30:48 2009 +0100

    Fix crashes with Icecast script and other service scripts.

    Since the QueryMaker was already set to autoDelete, I don't think we
    should delete it again. This deletion often triggered a double-free, as
    far as I can tell. Max, if you think this is wrong, please let me know.

Let's re-open this case for a moment.

My amarok played normally until a couple of days ago when it started to have horrendous crashes from code 11 segmentation faults. The situation was so severe I counted fifteen plus segmentation crashes in forty minutes during one session before I stopped counting.

Yesterday, besides having segmentation faults, amarok began skipping down the playlist from one station to another and would not stop skipping until I looged amarok off.

Today, Mar 11 2010, amarok would not play for me but skipped starting off from station to station ( without any audio ) ... Why does it do this? amarok 2.2.2 has been touted, to me at least, as having the segmentation bugs removed but they are still there.
