GnuCash error during printing

[cool65]

Hi,

i've a problem with gnucash v1.8.4. When i try to print, and i push the
print-button in the printing-box, only a message "could not find default
font" (something like this, it's a german message on my system) appears,
but no printing. It's the same, when i try to print in a file (ps or
pdf).

My system: 

SuSE 8.2 with needed patches
KDE 3.1.2
gnucash 1.8.4-0.pm.4 (packman)

What can I do?

thanx, christoph
