Comment # 1 on bug 907698 from Dominique Leuenberger

In openSUSE Tumbleweed, this issue has already been addressed; the signal
qiuality update has been changed to be debug output, rather than info output.

I added a patch to MM and submitted it to the GNOME 3.14.2 stack update; as
this is a rather minor issue (functionality is not affected at all), it does
not warrant for a speedier update than that imho.
