When using trac-admin to create a new environment with a mysql database
the program crashes with the following output:

/usr/share/trac/wiki-default/TracFastCgi => TracFastCgi
Failed to initialize environment. unhashable type

I think this has something to do with my mysql server. This is my
settings:

mysql> status
--------------
mysql Ver 14.7 Distrib 4.1.14, for pc-linux-gnu (i686) using readline
5.2

Connection id: 1453
Current database:
Current user: root@localhost
SSL: Not in use
Current pager: /usr/bin/less
Using outfile: ''
Using delimiter: ;
Server version: 4.1.14-log
Protocol version: 10
Connection: Localhost via UNIX socket
Server characterset: latin1
Db characterset: latin1
Client characterset: latin1
Conn. characterset: latin1
UNIX socket: /var/run/mysqld/mysqld.sock
Uptime: 1 day 2 hours 1 min 6 sec

I searched for similar errors but I couldn't find any and since it
seems to work with mysql for other users the problem should be in my
server. Should I try to upgrade to mysql 5? Any other ideas?

This is a bug in the MySQLdb library. See:
http://sourceforge.net/tracker/index.php?func=detail&aid=1518642&group_id=22307&atid=374932

They say it should be fixed in their SVN version, but I don't know if
there's a workaround for it.
