[Evolution] printing as user

[Anton Bretterklieber <anton br aon at>]

Hi *,
Trying to print mails as user I only get blank pages. Also the preview
shows this.
Printing as user in other applications works.

My system: SuSE 7.2, kernel 2.4.18. ximian-evolution1.0.5.1,
libgnomeprint11-0.25-ximian.7, libgnomeprint15-0.35-1.ximian.1,
gnome-print-0.35-1.ximian.1, gnome-print-devel-0.35-1.ximian.1
It seems, that there are set incorrect uids or gids. 
Where are they to be set?
Printing emails as root works.

Printing normally is done over cups.
thx
Toni
