improper image header for gif loop

[freshfey]

I've tried adding a loop to multiple files in a folder, starting like this:

convert ab-rollout-1.gif -loop 0 ab-rollout-1.gif

but I keep getting an error

convert: improper image header `ab-rollout-1.gif' @ error/gif.c/ReadGIFImage/1020.
convert: no images defined `ab-rollout-1.gif' @ error/convert.c/ConvertImageCommand/3257.

All of these images have been converted/edited with ImageMagick, so I'm not sure what's going wrong here.

I opened a Github issue, but I think this is the better place for the question, sorry for that.

We respond on both places. Can you reply to my github questions?
