Bug Details
-----------------
Many (but not all) of the mail headers are displayed as unread, with  
invalid address, [No Subject], wrong date and zero size (see attached  
screenshot). The exact number of these wrongfully displayed mail  
headers depends on the web browser I use (Firefox 25.0.1, Chrome  
31.0.1650.57 m, IE 10.0.9200 - all on a WIndows 7 64-Bit machine). But  
with all browsers there are plenty.
If I click on such a mail header the email content is displayed  
correctly in the lower part of the DIMP GUI and the mail header goes  
from unread to read. This status change is not saved on imap server so  
the next time I log in the certain mail header is displayed as unread  
again. In fact the such an email is already marked as read since long  
time (verified for instance through Thunderbird).

In the "/var/log/messages" log file there are many error messages that  
seem to do something with the aforementioned issue:

. . .
HORDE: [imp] PHP ERROR: Invalid argument supplied for foreach() [pid  
12699 on line 2594 of "/usr/share/php/Horde/Imap/Client/Socket.php"]
. . .

Just for completeness: if I login in Horde with Basic GUI mode  
(instead of dynamic) the mail headers are display correctly.
