No, it does not....
But nevertheless, you see what you see?

"__basicnew__" is a class method. It must be there independent
on the concrete object.

If it were not there, then whether or not you see the error
may depend on whether or not the index file is present (you
should not see it when there is no index file; you may, if there is).

But, it should be there. If not, then the shared object
"BTrees/_fsBTree.{so,pyd}" must have been badly executed
(maybe because it is corrupt) -- but it would be surprising
that this shows up in such a harmless way (one would instead
expect a memory violation or bad opcode or something really nasty).
