Unfortunately you've cut out all the information from report-emacs-bug
that might help us narrow this down. Could you provide the values of

system-configuration-options
system-configuration-features

(or just run `report-emacs-bug' again and paste the results into a reply to
this bug report).

Does this also happen when running 'emacs -Q -l .emacs', with .emacs
containing only your frame size configuration?

Thanks
