we should call these bugs virmin,

i wonder, if pdftex has a dangling pointer, we could add the vector at the
end of the file with that number as object and cross our fingers that
acrobat would 'reconstruct' the file, but i must admit that i never saw
acrobat being able to really correct / reconstruct a corrupted file.

Also, say that we should copy the font descriptor, add an encoding object
[both ascii], add an additional ref table, then we would have an updated
file [second obj ref number being 1 instead of 0] and this would be valid.
Of course the problem would be to identify the correct vector. A bunch of
such files could then be optimized by acrobat.
