Apologies ... this was a side effect of redefining 'Power' / the infix
operator ^ to do wedge products for differential forms.  Apparently
Inverse calls Power during this inversion, at least for some of the
terms (?).  Hence the bug.

The code worked when I wrote it (found it?) 10 years ago, ugly as it
was.  But mathematica changes since then make this old kludge fail.

Thanks to all who replied,
