Tell me what information is still needed.

A gdb backtrace would be more helpful. But you may have to rebuild with debug symbols enabled. But my guess is that we will find that it is crashing in whatever theme engine qtcurve uses.

Yeah, that looks like a bug in qtc. My guess is that it is attempting to access the children of a container before it has been fully realized. It seems to be doing this while I am attempting to realize some widgets.
