Yes, gnome.program_init() does bad things now. It changes the LC_NUMERIC
locale setting which is used to determine if "." or "," is
used as the decimal point.
See http://bugzilla.gnome.org/show_bug.cgi?id=135055
I had the same problems and fixed it like this:
program = gnome.program_init(NAME, VERSION)
# gnome.program_init has the bad new habit to modify the locale
# settings (bug #135055); repair it
import locale; locale.setlocale(locale.LC_NUMERIC, "C")

I fully agree. But the real problem is that Python uses locale-sensitive
libc-functions for parsing floats.
