error running git-completion.bash on snow leo

When I

source git-completion.bash

I get:

-bash: git-completion.bash: line 127: syntax error near unexpected token `done'
-bash: git-completion.bash: line 127: `	done < <(git config -z
--get-regexp '^(svn-remote\..*\.url|bash\.showupstream)$' 2>/dev/null
| tr '\0\n' '\n ')'

anyone know why?

latest os x snow leopard.
