probs with gnome-print

[Poldi Winkler]

Hello,
after a new installation of gnucash 1.6.8 with Guppi-0.40.3-214, and
gnome-print I have got problems with report, aktiva and passiva and
price diagram. After I use options an push ok, gnucash will be
closed/crashed.
The message I got on the console:
"GdK-Warning : Missing charsets in Fontset creation
GdK-Warning : ISO8859-15
** CRITICAL **: file gnome-font.c: line 188 (gnome_font_new): assertion
`face != NULL' failed.
I can't find the default fonts needed by Guppi.
In 99% of all cases, this means that there is a problem with
your installed version of gnome-print."
Now I have changed gnome-print (from 0.36 to 0.34, 0.32)  but the
problem is the same.
Can anybody tell me, what is the combination of gnucash 1.6.8, Guppi and
gnome-print or can I solve the problem in another way.
I have also changed the style in gnucash,setting, preferences and style
of the report - no change of the problem.
Thanks in advance!
