Summary: Double free/corruption?

Initial Comment:
Today I encountered a problem with system complaining on double free/corruption, but as I don't know C, I cann't say it's a problem with Python or with MySQLdb.
Attached is a stack trace that I saw in screen session termination window. I am unable to reproduce this error, I tried few times, but it does not happen.

If this is a MySQLdb (or even MySQL) problem, I'll report the bug as appriopriate, just let me know.

The system is pretty standard FC4. Below is as some system information, let me know if I should provide you anything more.

Since the top 6 or 7 stack entries are all in
/usr/lib/mysql/libmysqlclient_r.so.14, and shows it trying to using its own
free() function (my_no_flags_free()), it's almost certainly a problem in
the extension module (as opposed to in Python).
