Did you by chance change it to 0 or 100% ?

It needn't be 0 or 100%
I'm able to reproduce when I click somewhere to slider instead of moving with circle. But sometime I'm able to reproduce even with moving a circle on slider.
If you nedd any additional data abour hardware or something else I will be glad to provide them.
If you need a coredump I can provide it.

Output from valgrind
This seems to be a de-reference of NULL pointer.
sh$ rpm -q gtk3 xfce4-panel xfce4-power-manager
Does it help?
or do you need to see a coredump?

xfce-panel valgrind output
I can also see a use after free in xfce-panel but it should not be related.
It's a different process.
Can you try this scratch build:
from bug 1278746
and see if the problem persists?
It works for me and there isn't any valgrind error.
You can close this bug as duplicate.
