[imp] missing last_login value ... ?

[Marc G. Fournier]

'K, I'm confused ... I'm currently trying to get the demo site up to date,
debugged and a few modules added into it, and upon login, I'm getting:


Notice: argument passed to unserialize() is not an string in /usr/local/www/demo.hub.org/horde/imp/lib/Session.php on line 223


the code in question is:

./imp/lib/Session.php:223:            $last_login = unserialize($prefs->getValue('last_login'));

yet doing a search of all the source using 'grep -rn', I can't find it
defined as part of any of the sql files, bu tdo see it defined (I'm
guessing), in:

./imp/config/prefs.php:556:$_prefs['last_login'] = array(

If I go and re-login a second time, the error goes away, but getting it
the first time is kinda disquieting ...
