It looks like the problem is URLDispatcher is failing trying to launch the URL from the dash when the file lives in ~/Pictures:
** (process:2555): WARNING **: Unable to dispatch url 'file:///home/phablet/Pictures/IMG_2088.MOV':GDBus.Error:com.canonical.URLDispatcher.BadURL: URL 'file:///home/phablet/Pictures/IMG_2088.MOV' is not handleable by the URL Dispatcher
There are no denials in syslog. When moving the movie to ~/Videos, it's launched correctly by url dispatcher.
