[PyQt] Help tracking down intermittent segfault using QGraphicsItem

If I read you correctly, you are saying that this is probably
"fixing" the problem.

So, if I can get over not wanting the ugly warning, it's probably
safe to ship it like this.


I have gone through and everywhere I was throwing away
python references to old Qt objects I instead just hold on to
the old one, and that has reduced the chance of a segfault
significantly, but it still happens occasionally. So I'm still
searching for objects that are getting released too early.

Manually adding that one object to the scene seems to
fix it completely...


Thanks for your help!
