I see now that I had to work around this problem in TeXLive 2003 also. I
agree that it's likely to be a long-standing bug, but am not expert
enough to suggest where the root lies.
Akira Kakuto, referring to the bbold11.mf file that mktexfm(1) generates
and leaves in $VARTEXMF/fonts/source/jknappen/sauter, writes:

TeXLive 2003 supplied b-bbold.mf in
$TEXDIR/texmf/fonts/source/public/sauter, along with the other Sauter
Metafont files - 46 in all. TeXLive 2004 supplies the other 45 Sauter
Metafont files in $TEXDIR/texmf-dist/fonts/source/public/sauter but
omits b-bbold.mf. It is necessary to put that file back in the TeXLive
2004 installation (and run 'texhash') to make Akira's work-around above
work. I think we'd all be grateful to anyone who had a proper fix,
though.
The Blackboard Bold typeface is a historical fudge in any case - whose
origin is the pseudo-bold characters that mathematicians and others
wrote on blackboards with chalk because drawing proper bold glyphs would
have been too much effort. Some Blackboard Bold glyphs such as N, Z, R
etc. have, of course, long been adopted as symbols in their own right.
