Give that a try: Create a database copy and use a comma in the filename. For example, make a new copy of your names.nsf and name it names_for_PMR_12345,999,618.nsf. This will not work neither in Notes 6.5.x nor in Notes 7.0.x. There is SPR RSCR5V6BBG for that problem but nobody else did open a PMR for that problem yet so it is unlikely to be fixed ever.
