Please describe *exactly* what you did. Eg:

emacs -Q
M-x calendar
M-x customize-variable
etc etc

Please also try and reduce the diary-file to the minimum needed to
show the problem, and post it here.

And also do

M-x toggle-debug-on-error

and post the backtrace that you get when the error occurs.

Thanks.
