[horde] Missing required state object after update to 5.2

[Andreas Mauser]

Hi,

after updating to Horde 5.2 I get error

Message from syslogd at web at Jul 10 00:51:31 ...
 HORDE:[horde] Missing required state object [pid 1529 on line 122 of
"/usr/share/pear/Horde/ActiveSync/Driver/Base.php"]

again and again each second in the log until I stop the webserver.

I read that installing the horde_frameworg 'again' should help, but
didnt find out how to do that.

I am not able to logon to Horde anymore. I get to the login window,
enter name and password, but get error

Connection to e-mail server failed

and back to login screen again.

Any idea how to fix that?

Thank you very much,
Andreas
