According to a quick search, the author seems to have relicensed this to
LGPL2.1 in later versions; the version labelled "1.0 final" might be suitable?
See: http://www.twinhelix.com/css/iepngfix/

The s5 package has the same bug. Perhaps it would be possible to make docutils
use files from s5, and add Recommends: s5 (or Depends or Suggests, depending
how important you think rst2s5 is), rather than embedding a copy of the
S5 themes? If so, only the s5 maintainer would need to fix this.

According to source.debian.net this also affects cython, docvert, lxml,
plone3, python-chaco, plastex and jifty, although I haven't verified that
those don't already contain a license clarification in debian/copyright. All
of those seem to get iepngfix.htc via an embedded copy of S5, just like
docutils. I haven't filed bugs on them, but perhaps the s5 maintainer
should investigate whether they could share s5.
