[ingo] Ingo error in Groupware 1.1 (Ingo 1.2)

[Wolfgang Rosenauer]

Hi,

I've upgraded to Groupware Webmail 1.1 a few weeks ago.
Now one of my users reported problems with filtering (ingo).

It seems that he runs (at least) into the following issue:

PHP Fatal error:  Call to undefined method Ingo_Script_sieve::addblock() 
in /srv/www/htdocs/groupware/ingo/lib/Script/sieve.php on line 294

And indeed there is no addblock() function anywhere.

Is there a solution for that?

Thanks,
  Wolfgang
