Hm. You'll need to check your platform's locale settings, but I bet
that that setting implies LATIN1 encoding (or LATINsomething anyway).
So any message text that gettext produces that happens to contain
high-bit-set LATIN characters would be invalidly encoded in a UTF8
database. The particular case that causes error stack overflow is
where the message about invalid conversion itself has the problem :-(

The real bottom line here is that your locale settings have to imply
an encoding that is the same as the database encoding. This is just
one of the things that can go wrong when they're different.

"show lc_type" would tell you, but it's probably the same.
