Are you using some compiler trickery to force g++ to treat char as
unsigned char (in particular, are you using a customised CXXFLAGS)?

If not, this may be a glibmm bug because the standard library is
obliged to provide specialisations of std::char_traits (including
void std::char_traits<T>::assign(T&, const T&)) for the char type, but
not for the unsigned char type. However 'grep assign
glibmm-2.16.3/gio/giomm/*' and 'grep assign
glibmm-2.16.3/glib/glibmm/*' does not reveal anything particularly
supicious.  (I do not have glibmm-2.16.5.)
