[horde] login problem

[cyko at cykotix.com]

I just recently (now) updated my HEAD version of Horde/Imp.  Upon logging 
in, I get the following message now:

Notice: unserialize() 
[<http://www.php.net/function.unserialize>function.unserialize]: Error at 
offset 0 of 10 bytes in /usr/local/www/mail/webmail/horde/lib/Auth.php on 
line 412

Warning: Cannot modify header information - headers already sent by (output 
started at /usr/local/www/mail/webmail/horde/lib/Auth.php:412) in 
/usr/local/www/mail/webmail/horde/imp/redirect.php on line 140

Anyway to quick fix this?

Thanks.
