[guppi-list] broken gnome-print-installations

[Lutz Müller <urc8 rz uni-karlsruhe de>]

Hi!

First of all, guppi seems to be a very nice program - I am impressed :-)

Then, on my Debian/unstable system, guppi will crash after some
gnome-font warnings. I guess this is related to a broken gnome-print
installation? As I don't know how to fix that I tried to keep guppi up
and running in case of an error even without fonts. The resulting
one-line-patch is attached.

Now to the scatter-graph. I am missing the update-feature including the
possibility to create a graph without data and filling it through
updates. I had a look at it but it seems that the implementation will
result in a bigger (non-trivial) patch. Is someone already working on
that? 

Regards

Lutz Müller
