The following error will be raised: https://bpaste.net/show/1a4dbe75eb96

This is actually infinite recursion error, the incorrect error raised here is fixed in [PR 1244](https://bitbucket.org/yt_analysis/yt/pull-request/1244/remove-some-unnecessary-error-handling/diff).

h/t to @atmyers for originally discovering this error.
