Got a test script? When a connection is made to a Python slot the
reference count of the slot is not increased (never has been). The current
garbage collection is much more "correct" than in previous versions, so
(perhaps) it's exposed an existing bug rather than created a new one. Have
you been using previous snapshots, or were you using 4.2.1/3.14.1?
