[timeless]

it's common now.

i think it's a null pointer deref

0xc should be the third or fourth method from a null object.

I only see 13 of these crashes on any version in the past 4 weeks. Almost all of them are on 4.0b1. I am resolving as works for me unless anybody thinks this needs to stay open.
