ImageProcessor error playing GIF Collections

[go_robot_go 0]

I've created a Collection in Emby that contains half a dozen or so animated GIF images. Attempting to play or shuffle the collection causes the UI to spin forever (the "waiting" circle displays endlessly, and nothing ever happens). Looking in the logs, I find this error each time I attempt this:

Related (possibly), I've found that I cannot create a Playlist of GIF images, only a Collection. I can attempt to add them to a Playlist, but they are never actually added.

To be honest I don't think we've really tested animated gifs. Can you provide the image that is failing here for testing? Please zip it up to avoid the forum making any changes to it. thanks !
