Hello,

today I updated Horde via Pear. Among other packages Horde_ActiveSync  
was updated from 2.27.1 to 2.28.2

Now I'm getting these error messages:

2015-05-27T09:06:17+02:00 WARN: HORDE PHP ERROR: array_flip(): Can  
only flip STRING and INTEGER values! [pid 17864 on line 179 of  
"/usr/share/pear/Horde/Imap/Client/Ids.php"]

I enabled debugging:

12. array_flip() /usr/share/pear/Horde/Imap/Client/Ids.php:179
13. Horde_ErrorHandler::errorHandler()

I verified that these errors didn't show before the update.

Until now I don't see any impact on ActiveSync funtionality, but maybe  
something's wrong here.

If you need further information please tell me.

Best regards, Christian
