Hi Chris,

I had the same issue after upgrading today:

Sep 27 09:50:00 horde HORDE: [imp] PHP ERROR: Trying to get property of non-
object [pid 22694 on line 353 of "/var/www/horde/imp/lib/Imap.php"]
Sep 27 09:50:01 horde HORDE: [imp] IMAP error: Mailbox does not exist, or must 
be subscribed to. [pid 22694 on line 340 of "/var/www/horde/imp/lib/Imap.php"]
Sep 27 09:50:01 horde HORDE: [imp] PHP ERROR: json_encode(): Invalid UTF-8 
sequence in argument [pid 22694 on line 242 of 
"/usr/share/php/Horde/Serialize.php"]

However, I tried a different browser and it went OK. So I emptied the first 
browser's cache and the error vanished.
