Viewing folders that I know contain messages results in IMP showing  
them empty, with the following log entry:

2010-04-14 18:48:46: (mod_fastcgi.c.2570) FastCGI-stderr: PHP Notice:   
Undefined index: sort in /horde/horde/imp/lib/Mailbox.php on line 321
PHP Stack trace:
PHP   1. {main}() /horde/horde/imp/mailbox.php:0
PHP   2. IMP_Mailbox->buildMailboxPage() /horde/horde/imp/mailbox.php:227
PHP   3. IMP_Mailbox->_buildMailbox() /horde/horde/imp/lib/Mailbox.php:491

It doesn't affect all folders, but I can't pin down the differences  
between the folders that are working, and those that are not.

The value of $res in Mailbox.php is:
array
   'match' =>
     array
       0 => string '31351' (length=5)
       1 => string '31357' (length=5)
       2 => string '31358' (length=5)
...

The working folders contain the sort element, as the code is expecting:

'sort' =>
     array
       0 => string '43858' (length=5)
       1 => string '43857' (length=5)
       2 => string '43856' (length=5)
       3 => string '43855' (length=5)
....
