I'm not able to reproduce. both content and plugin plugin-containers shut down for me.

This plugin is obsolete as well. The installer places the files in the application directory which we don't support by default. ('plugins.load_appdir_plugins' needs to be set.)

The main browser is hung waiting on a window to get destroyed. Usually this means Windows is waiting on something to happen in the plugin process associated with the child window. Could be caused by a shutdown hang in the media player, or maybe there's a deadlock in out content process + plugin ipc taking place.
