Comment 1 Mikko C. 2010-03-18 10:25:57 UTC 
The backtrace seems similar to the one in bug 229240 with some line changes due to different QT version.
So I guess this isn't fixed?
Comment 2 langstr 2010-03-18 12:04:27 UTC 
It's possible that it has the same underlying cause, because reading the Qt source code it seems to involve a QPersistentModelIndex yet again.

But the path is completely different.

Hint to people trying to reproduce this: the lines in the crash dump indicate that an item edit was being started. You may need to move the mouse while you're double-clicking, to make it an item edit instead of an item select.

I can not reproduce this (Qt 4.6).

Interesting observations:
  - The crash dump does not contain any Amarok class names; it's all underlying generic Qt classes.
  - The crash dump is extremely similar to the one of Leo Franchi in comment #3 of BUG 228214. That went away when he upgraded Qt.
  - It runs aground at the very first QSortFilterProxyModel. That must be GroupingProxy, which is a dumb 1:1 passthrough of rows.

I don't know the PrettyListView code well; it might be doing something nasty somewhere.

But given the observations, I think that there's a significant chance of a bug in Qt.
Comment 3 langstr 2010-03-18 12:12:52 UTC 
Ah! Qt 4.7 is not yet an official release of Qt, if I understand correctly?

That would strengthen the suspicion.
