 Hi dev,

 today I discovered that g.gui.animation fail to create gif image.

 Until few weeks ago it worked really well, the error that we (my colleague
 told me this problem and I'm able to replicate it) discovered is the
 following


 {{{
 must be string or buffer, not None

 Reason: must be string or buffer, not None

 Traceback (most recent call last):
