This bug seems to be deeper in the system than just the indicator. Apart from the mentioned error, I get utf8 errors in most Gtk Python programs ("'utf8' codec can't decode byte 0xca in position 0: invalid continuation byte") and Nautilus reports "Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()" for everything.
