per page = 0 causes FloatDomainError:Infinity when total_pages is called.

[mserran2]

next_page, previous_page and total_pages all cause an Infinity error when to be thrown when the per_page variable is set to 0.

FloatDomainError:
   Infinity
 # ./lib/will_paginate/collection.rb:16:in `ceil'
 # ./lib/will_paginate/collection.rb:16:in `total_pages'
 # ./spec/collection_spec.rb:83:in `block (3 levels) in <top (required)>'

I can confirm that this is still an issue. Any reason it has not been released?

Same issue here.
Also occurs on passing empty string as per_page value.

Just need to check that you got proper integer value before passing it to paginate.
