I had a similar problem with trying [gf/gl]'s get. It works when 
[gemwin]'s 'create' method has been called, but if you try 'get' before 
that, it crashes. What should I do ?

I think it's fine to check it at every call. Such a check is fast enough 
considering the relative speed of the rest of pd. If there are lots of 
them, I may replace them with a small macro, but in the executable, it 
will amount to exactly the same.
