If the code you posted is really the only relevant code and entry is a
Hash, then no.

irb(main):003:0> my_big_hash = {}
=> {}

Empty.

irb(main):004:0> puts "x" if my_big_hash[:foo].nil?
x
=> nil

As expected.

irb(main):005:0> my_big_hash
=> {}

Still empty.

irb(main):006:0> my_big_hash[:foo].any_method
NoMethodError: undefined method `any_method' for nil:NilClass
	from (irb):6
	from :0

Still getting an error.

So either your entry object is not a basic Hash, or something else is happening.
