No luck at all for me too.
Same nasty SQL/DB Error using IE5 (win) Firebird-0.7 (linux) but OK with IE6 (win) Mozilla-1.5 (linux).
It seems that if I run WP under https://my-host.com the bug is gone, I get it when I use my subdomain
https://www.my-host.com. I only tried with Firebird-0.7 (linux) though.
