You'll be far more likely to get help if you give some basic details.
WhIch Emacs version are you using (M-x emacs-version)?  What major mode
are you in?  What minor modes (if any) are active?  What did you ACTUALLY
DO (exactly which keys did you press) to cause the error.  Can you make
the error happen in a small enough buffer to post?  If so, do it!

The idea is to help somebody reproduce the error with the minimum amount
of work.

Incidentally, there's a section on bug reporting in the Emacs Manual on
page "Bugs".  To get to it, do C-h i, m emacs, g bugs.
