Hello to everybody!
My program is occasionally crashing in QQmlVMEGuard:

@And I have no idea how to even debug it... It seems to be crashing somewhere in QAbstractListModel subclass or TableView, but I can't make it reproduce stable in the same place, sometimes it shows all data, sometimes crashes even if I have no data at all.
What You can recommend?
Qt 5.3.1, tried under OSX, Win and Linux. The same result...

Hi,
You should rather bring this on the interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented
