Circle display object not available on Android build 591?

I’m having a weird issue:
For some reason, when running on Android Device rather than simulator, my circle display object is disappearing - both the graphical representation and the physics object. I’m guessing display.newCircle returns nil (so physics object cannot be created either - circle shape works in other instances).

E.g. some code in question:

[code]
– Creates rectangle (this works).
local rect = display.newRect(layer, x, y, w, h)
physics.addBody(rect, “static”)

– Creates circle (doesn’t work on device, but does work in Windows emulator).
local circle = display.newCircle(layer, x, y, r)
physics.addBody(circle, “static”, { radius = r })
