Chrome crashes on wrapper update

[davidben]

This is pretty annoying. If the wrapper <-> viewer interface changes, Chrome seems to have a habit of crashing on wrapper update. Perhaps it tries to detect plugin changes or something crazy like that?

This happens even when the plugin process isn't running, which is particularly odd.

Chrome does indeed refresh the plugin list when plugin directories change. One possible cause is that perhaps Chrome is unable to unload and reload the new wrapper in the plugin probing step (which happens in the browser process), so we get old-wrapper/new-viewer somewhere. #36 would help here.

Unfortunately this thing is resisting all attempts at giving me debugging information.

Definitely happening somewhere in plugin probing.
