How to repeat:
Try 
SELECT count(*) FROM 
with a table that has been deleted.

Thank you for the bug report. I couldn't repeat on Windows Vista X86_64 it was the table on local or remote server?. Thanks in advance.

The table was on a remote server (MySQL 5.0 on a Windows 2003 server)
[25 Mar 2010 12:31] Susanne Ebrecht 
MySQL server 5.0 is very old and unsupported.

Please try actual server version (5.1) here.
