Comment 3 Mark Kretschmann 2009-10-08 12:47:17 UTC

I cannot reproduce this crash with Amarok from git master.

Comment 4 Mikko C. 2009-10-08 13:09:45 UTC

can't reproduce it anymore either, Simon do you have a way to reproduce it?

Comment 5 Mark Kretschmann 2009-10-08 14:20:29 UTC

I was just able to reproduce the crash, by moving the root item only a few pixels. Debug and backtrace:


amarok:   BEGIN: PopupDropper* PopupDropperFactory::createPopupDropper(QWidget*)
amarok:   END__: PopupDropper* PopupDropperFactory::createPopupDropper(QWidget*) - Took 0.00095s
amarok:    Initialized thread, count== 4
amarok:    After the drag!
amarok:    clearing PUD
amarok: END__: virtual void CollectionTreeView::startDrag(Qt::DropActions) - Took 0.2s
KCrash: Application 'amarok' crashing...

Comment 6 Maximilian Kossick 2009-10-08 22:07:01 UTC

I'm not able to reproduce this issue at all.

Mark, the backtrace is quite useless as it points to a macro in
SqlQueryMaker. Can you replace the macro with actual code and get a
proper backtrace?

Comment 7 Mark Kretschmann 2009-10-09 20:44:07 UTC

Max has just committed a possible fix for this problem. Please test.

    attempt at fixing crashes in CollectionTreeItem (not reproducable by me unfortunately) by removing a potential race condition

Comment 8 Maximilian Kossick 2009-10-09 22:39:54 UTC

that would be unexpectd to say the least. The backtrace shows a crash
in sqlquerymaker, not in collectiontreeitem

Any news on this?

Comment 12 Myriam Schweingruber 2009-11-21 09:29:17 UTC

OK, closing for now as nobody can reproduce this with current Amarok 2.2-git. Make sure you have a patched GLIB version, see also here:
