Our application doesn't work with Debian packaged Python
Good they all,
Our program is an archiver for gnome that uses gnome-python with one
widget written in C.
I converted our program to autoconf and automake so anyone can (and please
do!) compile it and see what I mean.
Everything compiles fine. But when it runs it just throws a weird
exception.
The funny thing is, if I alien RedHat 6.2's python package, and install
that, it works! I need to change nothing else. Only the python package.
I then went and look at the source rpm. They have this patch in there:

Sure enough this fixes my problem. The thing is that this means our
program only works on Redhat (and who ever patched python 1.5.2 with this).
So what can I do now? How can I get this patch into debian-python? How can
I change my program to not need the patch?
btw the program is garchiver, it will be hosted at sourceforge as soon as
they get back to me, in the mean time I will mail anyone a copy of the
sources.
