I started emacs with '-Q' option and got following backtrace.

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
  ruby-move-to-block(1)
  ruby-end-of-block(1)
  funcall-interactively(ruby-end-of-block 1)
  call-interactively(ruby-end-of-block nil nil)
  command-execute(ruby-end-of-block)
