I don’t know why you made up your mind on this without having any details. The person reporting is the author of a graphics editor, he damn well knows the difference between a bug in his own editor and system frameworks. The issue seems to be with opening the GIF via default system frameworks, not anything special the editor is doing. Chances are it will affect any other programs using the same frameworks, maybe even GIF viewers.
