Thanks. That wasn't the greatest code anyway, so thanks for pointing me at it.
I couldn't reproduce the bug and didn't find anything suspicious under
valgrind, so I just committed a cleaned up version of some code parts that may
have lead to the problem and I hope that changes the refcount behaviour also.

Could you retry with the current trunk version?

Thanks again,
Stefan
