trac: already updated: Error binding parameter 3 – probably unsupported type

I’m sick today, but, here is a short one.

If the user cannot log in into trac after a self password reset and you receive this message:

user.name already updated: Error binding parameter 3 - probably unsupported type.

all you need is to delete the cached users session in the sqlite database.

First make a backup:  cp trac.db trac.db-backup
Now you have to find the sessions stored in the database:
sqlite2 trac.db
select * from session_attribute;

Find the user with the problems and delete his data:
DELETE FROM session_attribute WHERE sid = "user.name";

Now test.
Please do backup the database first.
