 New Comment:

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Aswell as a backtrace would help give some insight on the matter for
the maintainer

I'm willing to patch, submit traces etc :-)


Reproduce code:

Code probably irrellevant.

Expected result:
----------------
No errors in the log
