Thanks Louis,

You're right, I do get a message when running with --debug (which I
thought I tried, I must have missed it somehow):

[WARNING] At ~/Desktop/gup-opam/gup-test/packages.dev/gup/gup.opam:8:19:
            Expected a list of constraints

So that would definitely have pointed me to the problem if I'd seen
it. I can see why you might not show that to a casual user of a broken
repo, but it'd be great to see this warning more prominently on pinned
packages.

Thanks,
 - Tim
