I have had trouble with the following for a long time, now including VM
5.32.  My Unix mailbox is in mmdf format.  I have read and expunged all
the mail in my VM inbox, so the inbox file has been deleted.  I get new
Unix mail and try to get it with the VM "g" command.  I get the inbox
displayed with the mmdf "^A^A^A^A" separators, and VM says there are no
messages, and I got the following traceback:

Signalling: (wrong-type-argument arrayp nil)
  aref(nil 0)
  (aref ...computing arguments...)
  (or ...)
  vm-vheaders-of(nil)
  (narrow-to-region ...computing arguments...)

  (let ...)
  (let ...)
  vm(nil nil)
* call-interactively(vm)
  execute-extended-command(nil)
* call-interactively(execute-extended-command)

If I quit out of VM ("q" command) and then restart it (ESC-x vm),
everything is fine (quitting wrote out the inbox in mmdf format, so when
vm restarted there was an inbox in a format it recognized).
