Ludwig, you had several things set falsely which I tried to correct according to my knowledge. For me the bug assignee "Max Lin" seems not to appear as one of the openSUSE maintainers for libqt4 and libqt5-qtbase (you had mentioned libqt4 in your initial comment#0) according to what 'osc' shows. I do not have your special knowledge that "Max Lin" is the actually right assignee here and that this upstream issue is actually a bug in openSUSE.
