[PATCH] Crash on nonexisting can_handle_multiple_files property

[Martin Wehner <martin wehner epost de>]

Hi,

here's a patch that prevents a crash when the can_handle_multiple_files
property isn't provided by a bonobo property provider.
That's the case for the Totem property page atm - when you select
multiple video files and try to open their properties, it dereferences a
null pointer.
