[horde] imap_cilent error after pear update

[erling at eph.dk]

Hey
Can some one point me in the right direction please?

I did a pear update very late yesterday.
Now I have this eror in my php.log

[03-Jul-2014 09:35:49 UTC] PHP Fatal error:  Class 
'Horde_Imap_Client_Namespace_List' not found in 
/usr/share/php/Horde/Imap/Client/Socket.p
hp on line 329
[03-Jul-2014 09:35:49 UTC] PHP Fatal error:  Call to undefined method 
stdClass::getTimer() in /usr/share/php/Horde/Imap/Client/Socket.php on
  line 4262

When i try to login via login.php I get a blank page
And apache is logging a error 500 Internal server error.

Horde test seems ok,
db is migrated,
horde and apache has full access to /tmp.
APC cache seems to be running fine.
