I added a comment on bugzilla, too.
While adding additional logs to the bugzilla entry I realized that one
commit has not been tested.

good: 804f98e224e41c16e3b70f97790f84894745a392
untested: 2b989ab9bc89b29dd4b5509408b8fa42337eda56
bad: f90584f4beb84211c4d21b319cc13f391fe9f3c2

I do not understand why git bisect told me there is no remaining commit to test.
