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.
Comment 16 Lukas Slebodnik 2016-01-02 12:42:37 UTC 
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
gtk3-3.18.6-1.fc23.x86_64

Comment 19 Lukas Slebodnik 2016-01-26 12:56:07 UTC 
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.
Comment 21 Kevin Fenzi 2016-01-26 18:19:19 UTC 
Can you try this scratch build: 

https://koji.fedoraproject.org/koji/taskinfo?taskID=12682519

from bug 1278746

and see if the problem persists?
Comment 22 Lukas Slebodnik 2016-01-26 19:16:54 UTC 
It works for me and there isn't any valgrind error.
You can close this bug as duplicate.
