Wait, I suddenly remembered a change in GLib I recently stumbled over
while studying the ChangeLog:

Tue Aug 20 16:01:03 2002  HideToshi Tajima  <hid...@su...>

	* glib/gconvert.c (strdup_len): validate 'len' argument properly
	for the case that input string is not null-terminated. (#91222)

That would explain why a) the weird c_str() + normal output combination
works: c_str() appends the '\0' termination character.  And b) why it
works if the locale charset isn't UTF-8: strdup_len() is only called if
no conversion is necessary (it just copies and validates the input).

So I'm pretty sure this is your problem.  Grab GLib (branch glib-2-0)
from CVS or wait for the next release.  They already bumped the version
number to 2.0.7 in CVS, so it can't be too far off.

Cheers,
