[Thuban-list] [Thuban-announce] Thuban development release 1.1.0

[Serviopa]

I've compilded it in Mandriva 2005 LE with wxPython 2.6.1. When I try to
start
it, I get this error:

Traceback (most recent call last):

t = t.encode(Thuban._internal_encoding, "replace")
LookupError: unknown encoding: pt_pt

My system's locale is pt_BR, not pt_pt, so why Thuban try to use pt_pt?
Also,
how to bypass it?
