when I start hs-minor-mode and use S-mouse-2 to folding the program, an error occur.
wrong-type-argument stringp nil
the debug information is
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  looking-at(nil)
  hs-inside-comment-p()
  hs-already-hidden-p()
  hs-toggle-hiding()
  hs-mouse-toggle-hiding((S-mouse-2 (#<window 9 on clsAvsSequence.cpp> 171 (10 . 85) 48293437)))
* call-interactively(hs-mouse-toggle-hiding)
 
But I can't understand the debugger message.
Would anyone help me?
