Comment # 5 on bug 1161339 from QK ZHU

This is caused by https://bugzilla.gnome.org/show_bug.cgi?id=795940
And it was already fixed in 3.30 or later, that's why SLE-15-SP2 works fine.
SLE-15-SP1 (Update) is also affected though I didn't verify this on a SP1 VM
box.

The upstream bug conatins 8 commit, I will look into it and backport the
necessary commits to Leap15.1/SLE15-SP1.
