suspend in the lock/logout widget doesn't works

on my Laptop=Dell latitude E6510, RAM=8Gb, GPU=GT218 NVS 3100M, CPU=i7 Q 720 @ 1.60GHz running opensuse leap 42.3, plasma 5.10.95, KDE frameworks 5.38.0, KDE applications 17.08.1, Kernel 4.4.87-25-default, nvidia drivers, libreoffice
as in the title, the suspend button from lock/logout plasmoid/widget doesn’t works, the one in kickoff>power session yes and the other in kickoff>favorites (that I don’t remember how to put there) works.
how can I have the lock/logout plasmoid/widget working??

It looks like I can reproduce the issue here, simply nothing happens when clicking on it.
Can you report the bug on

That bug just got fixed today, patch backported to plasma-framework 5.38 in KDE:Frameworks5 and submitted to Tumbleweed.
