When does that error appear?  Directly during startup?  If so, start
emacs as "emacs --debug-init" which will put you in the debugger when
the error happens.  Post the backtrace shown there.

If it happens later when you do some specific action, do M-x
toggle-debug-on-error RET before doing that action.  That will likewise
put you in the debugger when the error happens where you can copy and
post the backtrace.
