Yes I think you should. The error buffer is a good way to pass back info that
you can't get after-the-fact so we should try to use it. I certainly will
appreciate if you can fix your case and send us a patch.

There is however no guarantee that the error buffer _will_ be used so your
work-around seems like a decent fix anyway. I'm convinced we have more error
paths that never stores anything in that buffer...
