I noticed the crashes of guppi on ppc never made
it into the guppi bug list. However for everyones
information, I built the current package sitting
in incoming on Debian ppc sid and the crashes appear
to be gone now. I didn't see an explicit mention of
a ppc fix in the changelog for guppi however there
is a va_list related fix that looks like a likely
candidate.

ps I am unaware if these crashes were ever duplicated
on other non-intel arches.
