1. insert Audio CD
2. Start AMArok
3. Try To Play a Track from the CD

log of amarok -debug --nofork
I was just testing wether amarok audio CD support was working (because of some complaints on the opensuse ml) but i just found amarok crash
amarok was playing music fine before (so i doubt that those crashed tables were crashed before)
I can't reproduce this here with latest git. What doesn't work is the detection of an already inserted CD, but that is another problem. Closing correctly. *** Bug 290542 has been marked as a duplicate of this bug. *** Reopening based on bug 290542 Created attachment 67859 [details]

amarok (2.5-GIT) on KDE Platform 4.7.4 (4.7.4) using Qt 4.8.0
I tried this again today with current git and had it crash again:
i have no idea how those Qt datatypes are supposed to look, but this is what i get:
the cd i inserted has 12 tracks, so i think whatever fills that map inserts crap, or was not done yet?

*** Bug 296288 has been marked as a duplicate of this bug. *** *** Bug 297621 has been marked as a duplicate of this bug. *** Git commit a3d378de5aca583bbbc13d1966df258f27e7f174 by Matěj Laitl. Committed on 07/05/2012 at 23:31. Pushed by laitl into branch 'master'. AudioCdCollection: don't create a reference out of temporary var (crashfix) There's following code in AudioCdCollection::updateProxyTracks(): const QString &urlString = url.url().remove( "audiocd:/" ); Which I think is wrong, because url.url() returns a temporary QString and QString::remove() returns a reference to itself. However, the temporary is AFAICS destroyed as soon as this line ends. This IMO results in urlString being an invalid reference. I'm not really sure about this, I haven't read C++ spec, but given many users report crash on the following line, this could be the culprit. I was never able to reproduce the bug, so I'm shooting blindly. Reporters, please test reproducibility with current git and reopen if this is not fixed.
