[pygtk] Application name is '-c'

[Frédéric]

In several places, instead of having my application name, I get '-c'.
It can be on warnings, like:

(-c:24058): Gtk-WARNING **: Locale not supported by C library.
        Using the fallback 'C' locale.

or in the taskbar of my KDE desktop (only when 2 or more windows of the
application are opened).

Any idea?
