[imp] [IMP] IMP suddenly stopped with expected end of data

Sun Mar 22 19:48:37 UTC 2015

Hello List,

I've got two instances of Horde/Webmail edition (5.0.4) installed on  
two distinct servers, both of them connecting to the same IMAP server  
for mail management via IMP.
Everything worked fine for a (long) while till last week: one of my 2  
instances generates an error each time I try to access IMP (other  
Horde applications still work well).
When clicking on IMP menu, I get the following error message:

Erreur IMAP sur le serveur.

In IMP.log file, I have the error lines:
2015-03-22T17:33:24+00:00 ERR: HORDE [imp] Erreur IMAP sur le serveur.  
expected end of data [pid 6778 on line 412 of  
"/homepages/23/d453220882/htdocs/imp/lib/Imap.php"]
2015-03-22T17:40:55+00:00 ERR: HORDE [imp] Erreur IMAP sur le serveur.  
expected end of data [pid 17195 on line 412 of  
"/homepages/23/d453220882/htdocs/imp/lib/Imap.php"]

By adding some traces in Imap.php at line 412, it seems that dynamic  
call to method 'islistMailboxes' is generating the error.

Any idea on what could be the origin of this error? My other instance  
of Horde works fine. Of course I didn't apply any change to the Horde  
repository and files.

Thanks

Frank
