New Comment:
I know this is hard to debug, but the complexity of the involved
classes simply can't be boiled down to a single script, unless I
exactly know where the crash happens.
I tested disabling mbstring right after submitting the report and
indeed the segfaults don't happen anymore.

Perhaps you can also check with valgrind, and running apache in single
process mode (-X).

You really should provide short example script..debugging using
something like IMP is PITA..
Anyway, does this happen if you disable mbstring?

Description:
------------
Again, no script to reproduce, this happens while parsing a compley
mime message in IMP.
