Hi,

while playing with ActiveSync and a Nokia N900, I noticed this error  
message in the logs:

2013-08-08T17:11:51+02:00 WARN: HORDE [horde] PHP ERROR:  
array_combine() [<a  
href='function.array-combine'>function.array-combine</a>]: Both  
parameters should have an equal number of elements [pid 8511 on line  
3603 of "/datastore/share/pear/Horde/Imap/Client/Base.php"]


The array_combine() call is inside Horde_Imap_Client_Base::resolveIds().

I've added this debug logging code:

          }

          return $res['match'];

The corresponding output:
