[RCU] Weird default_host behavior

I've discovered that, in my SVN checkout of roundcube, something strange is going on. If I specify that my default_host is 'localhost', things work just fine, but if I specify that my default_host is something else... ANYTHING else (such as my hostname), Roundcube will report that all folders have three new messages in them. Nothing else appears to be affected (i.e. opening the folders and reading messages works fine, it's just the unread-count that's wrong).

This is particularly frustrating for me because I host multiple domains with slightly different IMAP preferences, and I need to be able to connect to other domains on my server.

Does anyone else have the same issue? Or know of a fix?
