I count 285 different files with this problem (or 487 if duplicates
are included).

But I've since found that there are files suffering from this problem
with fill-opacity different from 0.75, e.g., scorpion-md-v0.1.svg and
addressed_envelope_with_stamp_01.svg.  This increases the total to 406
images (or 628 if duplicates are included), if the transparency really
is unintentional in all of these.

For the more general case

               s/fill-opacity:0[.0-9]*;/fill-opacity:1;/g

would presumably do it.

I found while looking at these files that some of them are also
suffering from Inkscape bug #1048268, so that they don't display
at all with Adobe or Batik.  This bug can be fixed by removing all
occurrences of the line
      inkscape:collect="always"
in files that do not have the string "xmlns:inkscape".

Another of the files (otto_02.svg) won't display because it uses
sodipodi:absref without xmlns:sodipodi - presumably another Inkscape
bug, though this one doesn't seem to have been reported, so it may
still exist in Inkscape 0.40.
