Fixed in HEAD and 4.1.2 (and MIMP 1.0).

After upgrading imap in 2.3.6 i got the warning :   Cannot use a 
scalar value as an array in 
<b>/applis/Internet/horde-3.1.1/imp-h3-4.1.1/lib/IMAP/Client.php</b> 
on line <b>656</b><br />



this is due to two consecutive values with the same keys in the imap 
Capabilities.



here is the detail of the capabilities (the SORT fallowed by   
SORT=MODSEQ was the problem) :



     [0] =&gt; *

     [1] =&gt; CAPABILITY

     [2] =&gt; IMAP4

     [3] =&gt; IMAP4rev1

     [4] =&gt; LITERAL+

     [5] =&gt; ID

     [6] =&gt; AUTH=PLAIN

     [7] =&gt; SASL-IR

     [8] =&gt; ACL

     [9] =&gt; RIGHTS=kxte

     [10] =&gt; QUOTA

     [11] =&gt; MAILBOX-REFERRALS

     [12] =&gt; NAMESPACE

     [13] =&gt; UIDPLUS

     [14] =&gt; NO_ATOMIC_RENAME

     [15] =&gt; UNSELECT

     [16] =&gt; CHILDREN

     [17] =&gt; MULTIAPPEND

     [18] =&gt; BINARY

     [19] =&gt; SORT

     [20] =&gt; SORT=MODSEQ

     [21] =&gt; THREAD=ORDEREDSUBJECT

     [22] =&gt; THREAD=REFERENCES

     [23] =&gt; ANNOTATEMORE

     [24] =&gt; CATENATE

     [25] =&gt; CONDSTORE

     [26] =&gt; IDLE

     [27] =&gt; LISTEXT

     [28] =&gt; LIST-SUBSCRIBED

     [29] =&gt; X-NETSCAPE

     [30] =&gt; URLAUTH



the patch adds a condition in the test to see if the value is already an array
