Thanks. It looks as though there may be two bugs here:

* a bug in the metadata: we ask innoextract to extract files from
  setup_quake3_2.0.0.2.exe, but then we do not actually find all the
  files that our metadata says it should provide, possibly because the
  names seen in the archive (extras/help/manual/htmlpages/*) are not a
  case-insensitive match for the names we ask innoextract to unpack
  (Help/Manual/htmlpages/*);

* a bug in the g-d-p code: after that has happened, the g-d-p code does
  not recover gracefully, but instead tries to extract the same files
  from the same archive in order to provide some other file that might
  not actually be found. We should extract each archive at most once.
