Comment(by neteler):

 I tried on Fedora 20/64bit using the Pillow fix r:

 It starts the GIF export, a file of 13 bytes is generated:

 {{{
 file scan2013.gif
 scan2013.gif: GIF image data, version 89a, 800 x 497
 }}}

 but it crashes with

 {{{
 must be string or buffer, not None

 Reason: must be string or buffer, not None

 Traceback (most recent call last):
   File "/home/neteler/software/grass70/dist.x86_64-unknown-linux-
 gnu/etc/gui/wxpython/animation/controller.py", line 554, in _export
     duration=self.timeTick / float(1000), repeat=True)
   File "/home/neteler/software/grass70/dist.x86_64-unknown-linux-

 TypeError: must be string or buffer, not None
 }}}

 The same error as originally reported.

 AFAIK Luca uses PIL on Ubuntu while I use python-pillow 2.2.1 on Fedora.
 Since PIL is no longer developed, Fedora switched to Pillow.
