This took a while to figure out.  How to reproduce:

You need a directory with .rpm files in it.  Let's call that
/foo/bar/.  Then,

emacs -q
M-x shell RET
rpm --install /foo/bar/<TAB>

where <TAB> is you pressing the TAB key.  I get this:

Debugger entered--Lisp error: (void-variable regexp)
  signal(void-variable (regexp))
  completion--some...
  completion--nth-completion...
  completion-try-completion...
  completion--do-completion()
  minibuffer-complete()
  call-interactively(minibuffer-complete)
  ...
  apply...
  ...
  completion-in-region...
  completion-at-point()
  call-interactively(completion-at-point nil nil)

Very tricky to track down.  I think it's in the pcomplete code.
Specifically, it appears that it has something to do with this
pcomplete-dirs-or-entries in pcomplete.el, since I see that code on
the stack at the point of error.

If you omit the "rpm" part of the input, it does not happen.

Good luck with this one!
