Redmine

Hello,

My Redmine 3.4.5 can't display any info when checking a mercurial repository when I upgrade Mercurial from 4.5.3 to 4.6.

The following error is shown in production.log:

Started GET "/redmine/projects/nerdsarmy/repository" for aaa.bbb.ccc.ddd at 2018-05-09 21:07:37 +0200

The command that triggers the error:

All of this is back to normal when downgrading mercurial to 4.5.3
