speedbar throws error

Hello,

A few days ago I updated my xemacs21 (debian testing) packages and now my=
=20
speedbar throws an error:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  normalize-menu-item-name(nil)
  easy-menu-remove(("Speedbar" ["Update" speedbar-refresh t] ["Auto=20

Ok, so normalize-menu-item-name expects at least one parameter.

I suspect some version mismatch in the debian packages (or a bug in=20
speedbar...) and contacted the debian user mailinglist, but got no answer.
Now I hope that someone here can help me find out whats's wrong...

Many thanks,
