Not a recognised version-control URL

[Chris00]

When parsing the OPAM repository, OpamFile.OPAM.read raises:

[ERROR] At ~/.opam/repo/default/packages/pxp/pxp.1.2.7/opam:4:52:
  Not a recognised version-control URL
[ERROR] At ~/.opam/repo/default/packages/pxp/pxp.1.2.7/opam:4:52:
  Not a recognised version-control URL
Fatal error: exception OpamFormat.Bad_format(_, 0, "Not a recognised version-control URL")

Should it really result in the failure of the entire script or should rather the package (or better, just the field) ignored?

BTW, the URL given in pxp.1.2.7 is

https://godirepo.camlcity.org/svn/lib-pxp

which is a proper URL for SVN!

This problem explains why the package widget on ocaml.org front page is empty.
