[tex-live] Problem with 11pt Blackboard Bold in TeXLive 2004

I get the same error with TL 2003 and bbold11:

$ PATH=/usr/local/texlive2003/bin/i386-linux:$PATH
$ mf-nowin -progname=mf '\mode:=ljfour; nonstopmode; input bbold11'
This is METAFONT, Version 2.71828 (Web2C 7.5.2)
...
>> asc_height#-x_height#-0.30714bigcap#
! Unknown relation will be considered false.
...

I suspect the bug has been there "forever" and is in the original bbold
MF code.  The bbold files haven't changed, plain.mf hasn't changed, the
same jknappen bbold11.mf file is generated ... could always be a bug in
MF itself, but it doesn't seem likely.

Alan, do you have any inclination to look into this in the bbold MF
sources?  The bbold11.mf file is simply these two lines:
design_size := 10.95;
input bbold;

Thanks,
