The buffer you're actually viewing at this point is buffer 3.  The '#'
in "#h" means that is the "alternate buffer".  :ls! will show a '%' on
the line for buffer 3.

":bd 1" followed by a plain ":bd" will stop the cyclic behavior of
creating new buffers displaying the directory layout.

This behavior is indeed wrong and I'll forward it upstream.  Just wanted
to give a quick explanation of the mystery behavior. :)
