There is a regression in Imap_Client 1.4.2 regarding the handling of  
problems with the QUOTA backend.

What I did:

I downgraded pear-Horde-Imap_Client from 1.4.2 to 1.3.2 and it works OK.

I still see the json error in the horde.log:
---snip---
2012-02-10T11:08:14+01:00 WARN: HORDE [imp] PHP ERROR: json_encode():  
Invalid UTF-8 sequence in argument [pid 78886 on line 242 of  
"/usr/local/share/pear/Horde/Serialize.php"]
---snip---
Not related to the problem, but this error message is not helpful, it  
would be nice zhich seauence and from where.

With the old Imap_Client I got messages about the server not  
supporting the QUOTA feature. I was playing around with IMAP QUOTA  
support in my config before the update of the Imap_Client part. My  
IMAP server does not support the QUOTA command, and with Imap-Client  
1.3.2 it was logging this fact but didn't fail to display the mailbox  
list. With Imap_Client 1.4.2 and no quota stuff in the config, the  
mailbox list is displayed correctly too, so the update from  
Imap_Client 1.3.2 to 1.4.2 contains a regression in that this error  
message is not correctly logged with a graceful fallback in operation,  
but it fails with an unhelpful message and breaks IMAP access.

Bye,
Alexander.
