Sprite animation not playing right

I’m using unity 5.0.0f4 64 bit because I follow several tutorials that don’t work with 5.3

Wrong.jpg shows the problem but it is sliced correctly as shown in correct.jpg. Is this a known 5.0 problem or what is wrong there?

I’ve tried this with 5.3 too and have the same problem. Slicing it differently makes no difference.

found the problem the image was too long (15200px) for unity I cut it in half now it works. Should I make a bug report out of this?
