This is also happening for me running Trac 0.11dev, Python 2.4.2, MySQL 4.1.22.

comment:2 Changed 18 years ago by justinjohnson@…

I found the problem. In admin.py last_visit is being retrieved from the database as a long, but the date formatting helpers in trac don't handle the case of a long. They handle int and convert it to a datetime. So adding last_visit = int(last_visit) fixed it.

comment:3 Changed 18 years ago by justinjohnson@…

See the latest comment at http://trac.edgewall.org/ticket/4497#comment:4. It will be fixed in Trac to catch the case of a long.
