Ultisnips: Invalid line 'endsnippet'

I have recently been encountering this error for Python snippets:

An error occured. This is either a bug in UltiSnips or a bug in a

endsnippet

Interestingly, this problem only occurs for Python snippets. I am using the latest version of UltiSnips.

Do this: $ mv ~/.dotfiles/vim/snippets ~/.dotfiles/vim/UltiSnips

snippets is a reserved directory name and is expected to contain snipMate snippets, you cannot put UltiSnips snippets in a directory called snippets. See the docs for more information.

Ah good catch. To elaborate a bit more on the problem for other people that may encounter the issue:

I had both a ~/.vim/snippets and ~/.vim/UltiSnips existing at once (I was originally using snipMate and switched over to UltiSnips).At some point after an update, UltiSnips was trying to read the ~/.vim/snippets/python.snippets instead of the ~/.vim/UltiSnips/python.snippets. The problem was fixed by deleting my old ~/.vim/snippets directory.

Thanks!
