Oh, it is a bug in xwem, due to number of arguments changed in new
XEmacs for `read-from-minibuffer' function.  Simple patch is in
xwem-interactive.el change:

  (defun xwem-read-from-minibuffer (prompt &optional initial-contents keymap 
readp history abbrev-table)


  (defun xwem-read-from-minibuffer (prompt &optional initial-contents keymap 
readp history abbrev-table &rest notused)

Note that xwem redifines `read-from-minibuffer' to its own(for
workaround blocking in minibuffer when executing keyboard macro), when
XEmacs is about to enter minibuffer in xwem context.

And yes, seting `debug-on-error' to t and having XEmacs frame visible,
and having

  (add-menu-button '("File") ["KBD QUIT" xwem-kbd-quit t])

in .emacs, is the way i debug in xwem.
