Comment 20 for bug 937605

Changing to the latest version of UltiSnip helped.

I changed line Bundle 'UltiSnips'
into
Bundle 'SirVer/ultisnips'

what returned latest version from github with changelog reporting on top following lines:

 - Various smaller bug fixes.
 - New command to manually add a filetype to the list for the current
   buffer. *:UltiSnipsAddFiletypes*
 - New or improved snippets: snippets, haskell, bindzone, python, golang,
   json, html, coffee, coffee_jasmine, javascript_jasmine, ruby, php,
   markdown.

version 2.1:
 - Python interpolation access to text from visual selection via snip.v.
 - Support for transformations of ${VISUAL} texts.
 - New or improved snippets: python, tex, texmath, ruby, rails, html, django

and all works, as it should.

Thanks a lot. (I would anyway recommend to mark this bug as resolved and not invalid, as it would help anyone, who would install it from release and not from latest development version).
