[imp] Problem with expand names

[dromero at fiec.espol.edu.ec]

Hi!

I already have configurated horde/imp and all work fine, but a curious
problem appear when any user try expand an unexistent name in their compose
windows. The error message is:

Notice: Object to string conversion in /srv/www/htdocs/horde/lib/Horde.php
on line 69

Notice: Object to string conversion
in /srv/www/htdocs/horde/lib/Horde/Notification/Listener.php on line 119

Notice: Object to string conversion
in /srv/www/htdocs/horde/lib/Horde/Notification/Listener.php on line 119

When the name is correct all is fine.

Thanks
Dennis
