Minification Error

[ghost]

Line 168 of angular.hammer.js conditionally executes fn.call(...) if typeof fn === 'function'.
Corresponding code in angular.hammer.min.js only checks for existence, i.e. b&&b.call(...) where b is the fn variable from the unminified version.
This causes an error, as b is sometimes an angular object.
