Hard to tell what your issue is, either there is still a race condition or xembedsniproxy (or even ksensors) is crashing entirely on you. What's sure is that it was worse before this update, because the setting supposed to prevent race conditions was ignored entirely in Plasma 5. So please use bugzilla.redhat.com to report your bug.
I installed this update with:
sudo yum-deprecated --enablerepo=updates-testing --advisory=FEDORA-2017-6250e8f561 update
and I was able to remove the following SELinux-related packages:
I did the removals with dnfdragora, so I can confirm that dnfdaemon still works fine here (SELinux disabled).
Since the F25 build ended up with no tags somehow, I retagged it into
f25-updates-candidate for you (using
koji tag-pkg f25-updates-candidate python-sphinx-theme-alabaster-0.7.9-1.fc25 – any packager can run that, as
*-updates-candidate are not locked tags) so that Bodhi will allow you to push it.
