Yes, it's a similar report, but the submitter tries to fix the problem in
python-land instead of the .c file. As he says himself ;
+            # Similar to _mysql_Exception. Not perfect.

I attached the patch to a report in sourceforge ;

http://sourceforge.net/tracker/?func=detail&aid=3008217&group_id=22307&atid=374934

We just realised this problem a few days ago, after 14 months of mysterious
"why is the cursor.description None in python-land ? who silenced the
exception ?".

After a while, we finally managed to reproduce the problem with a simple
script, and a after a bit of digging, we found the missing check in
_mysql.c.

However, this was just last week, so no upstream versions have applied the
patch (yet..). Otoh, the project doesn't seem to be that regularly
maintained these days, hence I decided to also submit patches to debian and
ubuntu directly.

cheers,
eskil
