Did you read the bug description and the associate StackOverflow
question?  The bug is that when you put `kill' as the
`delete-selection' property value on `self-insert-command' the
region is not killed - it is not added to the `kill-ring'.  And
the first char to be self-inserted is not inserted.

This is not about the out-of-the-box behavior of self-inserting
in delete-selection mode, i.e., with the property value having
its default value.
