Galeon doesn't start anymore

[Riccardo Gusso <grick tiscalinet it>]

Hello,
I have just upgraded my debian (unstable) linux box and installed
packages mozilla-browser-1.2.1-9 and galeon-1.2.7-6, and now this one
doesn't start anymore: the error that I receive when I launch it from a
terminal window is the following:
rick murena:~$ galeon

Gdk-WARNING **: locale not supported by C library
/usr/bin/galeon-bin: relocation error: /usr/bin/galeon-bin: undefined
symbol: begin_assignment__13nsCOMPtr_base

Any suggestion?
Bye,
           Riccardo
