I tried to figure out something about this crash, but did not get very far. _endTopLevelGroupings is private or undocumented method in NSUndoManager, so I did not find any documentation on it in XCode. I suppose this crash happens because the Qt GUI is not running in the main thread, but my Qt on Snow Leopard is based on Cocoa, instead of Carbon, as it was in earlier (non 64 bit) releases.

So I am not sure if this counts as a bug in Qt -- since SL is rated Tier 2 for Qt 4.6 -- or if this our fault. Nokia writes they want to upgrade SL to Tier 1 in Qt 4.7. That might perhaps fix this problem...

Cheers,

Arne
