[PyQt] Memory error using QVariant with custom class, how to debug?

[Arve Knudsen]

I am getting a memory error (python: free: invalid pointer) on Ubuntu
when instantiating QVariant with a custom class, and I am simply stuck
at the moment (don't even know where the free'ed pointer comes from).
Therefore I would very much like some suggestions as to how I can
debug the QVariant wrapper.

Thanks,
Arve
