> do you still think we should backport to 2.7?
This is not trivial question. On one side, using PyString_GET_SIZE() with non-bytes object definitely is a bug. It is better to catch it earlier rather than hope on failing in the following code. On other side, adding a check for bytes can break existing user code that is passed now by accident. _PyBytes_Join() in 2.7 supports unicode objects.
I think that the fix should be backported, and the proper fix should allow bytes and unicode objects. But I left the decision on Benjamin.
