The only thing I can think of that you missed is window screen. :-)

Basically, any object or substance between the camera and light source, 
as well as components of the camera itself. However, I wouldn't expect a 
dust cloud to make a lens flare-like shape, it would probably just make 
a glow around the light source(unless it was something like magnetized 
iron dust in a planetary or solar magnetic field, in which case the 
particles might have a similar shape and orientation).
