As the title suggests on one of my characters the option to create a new background layer does not exist with "Blank" being the only one available.
When prompted to choose a background layer to edit, only the options of "Blank" and "Default" are available.

This character hadn't interacted with the background layer options prior to 2.71.

This error, to my knowledge, is one that happens when you create a new template that you don't add anything to. Even just a space avoids it happening, but the template just doesn't show up ever and is inaccessible if it doesn't have any CSS in it.

If you can confirm a way to reproduce this on the testing server, I can look into it.
