It works fine when logging in to the forum directly instead of going through Joomla.

I know...I'm just saying that the problem is still present in 1.1 Beta....
I haven't seen a change list so I don't know what issues should be fixed from 1.02a ...

I dunno if this is the best way to fix that error, but till now it is working fine:

edit Sources/Subs.php

around line 2536 u got:
if (SMF != 'SSI' && !empty($user_info['last_login']) && $user_info['last_login'] < time() - 60)

change to:
if (!empty($user_info['last_login']) && $user_info['last_login'] < time() - 60)

and bellow about line 2540 comment this lines:
                if (time() - $_SESSION['timeOnlineUpdated'] > 60 * 15){
                      $_SESSION['timeOnlineUpdated'] = time();

I found that you don't need to comment the that line at all and it will work fine with the change in the script above that line (in fact, I ran into an error with the above comment because of the added { )

Ooops my bad, I forgot to say, u gotta comment the " } " of
if (time() - $_SESSION['timeOnlineUpdated'] > 60 * 15){
                      $_SESSION['timeOnlineUpdated'] = time();

but do not comment the code between it. The reason I commented these lines is that above about 10-15 lines there is the exact same code, so it executes 2 times, there is no reason  to do that, cause it will "loose" some seconds of total time online
