[imp] imp 6.2 in Webmail 5.2.2 unable to add my private S/MIME Key

[Sören Mindorf]

Hello Jan,

sorry for the delay.

The debug log you can find here:

http://p.mit42.de/view/571c25b7

In the webserver log I can see:

-------
[Thu Oct 16 21:22:32 2014] [error] [client 91.106.131.68] FastCGI:  
server  
"/var/www/clients/client1/web21/cgi-bin/php5-fcgi-*-443-mail.mit42.de"  
stderr: PHP message: PHP Warning:  Invalid callback  
Horde_ErrorHandler::errorHandler, class 'Horde_ErrorHandler' not found  
in /usr/share/php/PEAR/PackageFile/v2.php on line 1896, referer:  
https://mail.mit42.de/admin/config/config.php?app=horde
-------

but this message is not new. :(

In my old certifikate which I tried to import right now it works with  
12 alternative names.

My new certificate has 13 alternative names in it.

Could this be the problem?

Regards,
Soeren
