@th8a What's your OS, and does the bug still happen in 2.2.4?

If so, can you send me a demo patch that uses the absolute minimum number of objects required to trigger the bug?
By absolute minimum, I mean less than ten objects-- then I'll probably be able to find the cause of the bug in about 5 minutes. I can also try to track it down in a more complex patch but it will take me orders of magnitude longer.
If you come up with a minimal patch to demo the bug post it here or on the issue tracker:
