[horde] Error after upgrading to Memcache-2.0.4

[Henning]

Hi,

I have so far used a memcache server with the default configuration of the
server and horde without problems. After upgrading the Memcache pear package
to 2.0.4 horde will for every page throw an  

EMERG: HORDE Could not connect to any defined memcache servers. [pid 1841 on
line 440 of "/usr/share/php/Horde/Memcache.php"]

I have reverted to 2.0.3 as a temporary fix and things work again.

Regards

Henning
