Hi Dan,

Thx for the analysis and report of this issue. I'll try to get back to it, but meanwhile, I asked Ruby upstream to backport the fix.
Comment 2 Vít Ondruch 2018-03-22 11:14:51 UTC 
SHould be resolved now, since I was able to scratch build rubygem-sup
Comment 3 Dan Callaghan 2018-03-22 22:50:40 UTC 
Thanks! It is indeed fixed in rawhide.

But this bug actually exists in F28 as well, with rubygem-rdoc-5.1.0-3.fc28. Sorry, I should have filed it against F28 in the first place. Is it possible to backport this fix to F28?
