I cannot reproduce this here.  Could you apply the patch below (by hand,
probably) and then do C-M-x inside the `completion--some' function to
activate this new definition and then reproduce the problem?  It will
hopefully give us a more complete backtrace.

PS: (minibuffer.el is preloaded, so using C-M-x will save you from
having to byte-compile the file and re-dump Emacs).
