FYI: I installed todays snap of 5.3 and I couldn't seem to reproduce the error.
 [2008-07-19 23:48 UTC] jan at ecotech dot se 
Why didn't I keep my mouth shut. Same error with 5.3.0-200807200030 - different script.

Updated the version in the report to 5.2.6 && 5.3.0-20080720-0030.
 [2008-07-20 00:14 UTC] jan at ecotech dot se 
final info - both are clean installations. Only activated modules were: mysqli and gettext.

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.

Your backtrace shows you're executing some code ....

Unfortunately I am not able to reproduce the code... I switched back to 5.2.6 and error stopped occuring. I'll repost if as soon as I find anything :|

Get back when you have a short reproducing script.
