Strange crash in plasmoid

[Thomas Fjellstrom]

I've gotten quite a bit further with my plasmoid, but I've hit a wall. I 
just can't seem to figure out whats causing a crash:

Somehow adding an item to a QGraphicsLinearLayout is crashing, and the trace 
I've been able to get from either valgrind or gdb really hasn't helped.

Has anyone seen anything like this before? So far I just can't figure it out.

I'll be stopping for today, hopefully a break will allow me to see it 
clearer (tends to help more often than not).
