Built-in template fails "lowdly" with exception

[Evgeniy Ivanov]

length_is filter causes an exception if it's used with None intead of something that has len() method. According to docs this should never happen (tags and filters fails silently).

Exception Value:  	

Caught an exception while rendering: object of type 'NoneType' has no len()
