g.gui.animation fails to export animation with python3 error

[veroandreo]

When I try to export a GIF animation from G7:g.gui.animation, I get the following error:

Traceback (most recent call last):

I recompiled my 78 rel branch installation yesterday and I still get the same error, was this backported??

I cannot test in dev because the new image collections broke the temporal database and I have to rebuild it.

I have backported it just now to relr78.

After the backport, I do not get this error anymore in 78 rel branch. Closing.
