probs with price scatterplot

[Poldi Winkler]

Hello,
perhaps anybody can help me:
I have used in the past the price scatterplot (Reports/Assetts & 
Liabilities/Price Scatterplot) without problems. But now - and I 
don't know why suddenly - gnucash crashes after I use the options 
in price scatterplot. 
"** 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."
I have installd gnucash-1.6.4 and gnome-print-0.29-61 - RPMs from 
SuSE-7.3.
Thanks in advance
Poldi
