TypeError during login when session.last_visit column is null

[anonymous]

This happens in 0.11.4 and 0.11.5. It occured after I inserted rows directly to session and session_attribute tables (email) for my new users. I left last_visit column blank. When I put some value into it the error disappeared!

I think Trac shuoldn't throw an error in such situation.

I have found the reason of the error during reporting this ticket :-) I leave it for others.

Even though you are not supposed to write directly to the database, we could indeed make the session code a bit more robust. Probably a one-line fix.

Fixed in [8665].
