Description
If there is an object that does got an attribute "length" which value is 0 jquery can not be used on it.
jQuery({length:0})
[]
jQuery({length:1})
[Object]
This is unexpected behaviour, horrible to debug and the source code does not provide a reasoning behind the check. (see function isArrayLike)
