I believe I start to understand now what was going on. To match
specifications for the "post" table, PfaEdit insterts three blank
charatcers at the start: ".notdef", ".null" and "nonmarkingreturn", and
then starts with the real glyphs present in the font file. Some fonts,
however, have an explicit glyph named ".null" at U+0000, which caused
confusion, as it got inserted between "nonmarkingreturn" and "space".

If I would have known this before, I could have corrected it even with the
old version of PfaEdit simply by deleting the ".null" glyph in the SFD
file. The new version of PfaEdit, however, does the same automatically.

I have now put the new versions of TrueType files on the usual location
<http://freesoftware.fsf.org/download/freefont/>. Please test them out.

With kind regards, Primoz
