Regular panic.crashes when retrieving e-mail

Question

My iPhone started to panic crash all 20-30 minutes when not being used about 2 weeks ago. Resetting and restoring it from backup didn't bring any change. I've also sent it to Apple for repair, but they said, they couldn't find anything.
Now I've found out that it seems to happen whenever it retrieves e-mail from the server. Now, that I deactivated push (which was only used by my Mobile-me account) it seems like it doesn't crash anymore – but that can't be the solution.
Here is, what the crash-log says:
