[Plugin: Just One Category] Breaks Graphene's Slider

Worked for a while ok, but now it breaks the Graphene theme’s slider. With every other plugin disabled, just this one enabled (so no conflict with another plugin), the slider box is empty. Disable this and it works. Haven’t looked into the why’s and howtos, just reporting my experience.
