Partials don't work with layout named 'document'

[sdomagala]

As states in topic, when you call layout like this and try to use partial, rendering hangs with no error whatsoever, with -d you can see it is trying to render those files, but loops infinitely.

I hit this issue also. In my case I was using other name as a layout.
The problem is when the partial uses a layout that includes the partial ;).
When you think about the problem seems obvious that it will generate an infinite loop, however it will be great to detect this case to let know the user how to fix it.
