 Hi,

 i am experiencing a problem with wordpress starting with 4.5 i think.

 Since this commit [1] i always get redirect loops on the home page. this
 issue seemed to be fixed, and i can confirm this on various wordpress
 instances.

 But one instance has a '''domain with a special character''' ("ö" - german
 Umlaut), and the problem persists there.

 Also i am not the only user who can confirm this issue [2].

 Currently i have to reset the line [3] to the old value after every update
 since it gets overwritten. This is not a solution, only a very bad
 workaround.

 Of course i already have tried to disable all plugins, themes etc. which
 could cause the issue. I can say, that the problem is not caused by the
 hoster since i have many wordpress instances running on the same hoster
 and no other does have this problem (and no other have a special character
 in the domain)

 Regards
