The problem is not in the Cheetah code, which does not get executed because of the validation error.
I think this a Galaxy bug which tries to validate the parameter values but interprets the value "None" of the library_type param as "no option selected".

I think this is due to the Python special None object being turned into the string "None" at some point in the Cheetah template code.
It may be possible to avoid this by a case variant, e.g. "NONE" or "none", but it may be safer to avoid this special word :(
