Comment # 7 on bug 1043502 from Tony Mechelynck

When I came home today, patches were available for (among others) Mercurial,
and after applying them the problem has disappeared.

=> VERIFIED.

I suppose this answers the NEEDINFO. If it doesn't, please give more specific
steps: before I saw that the bug was RESOLVED FIXED, I tried to find the
"package to be tried" mentioned in comment #3 but reached a dead-end at
http://download.opensuse.org/repositories/home:/tiwai/openSUSE_Leap_42.2/ with
nothing later than 2017-05-18 AFAICT. Maybe I took a wrong turn somewhere.
