Here you have: /cacti/graph_realtime.php?top=0&left=0&local_graph_id=7

(/graph_realtime.php[39]:get_filter_request_var(), /lib/html_utility.php[508]:die_html_input_error(), /lib/html_validate.php[64]:cacti_debug_backtrace())
Validation error for variable size with a value of null. See backtrace below for more details.

Note: I'm only able to reproduce if real time graph is running onpage and popup at the same time.
