Hi,

the (novice) admin of one of my trackers has erroneously created a 
user that has two email addresses in his email field, separated by a 
comma. Trying to view the user list web page now results in the error 
message below, and I am unable to change that field. The web 
interface should probably check for such illegal characters when 
creating new database entries.

Templating Error
exceptions.ValueError: too many values to unpack

Debugging information follows

In python expression "user.address.email() or default"
