> If this file doesn't exist, WebKitPluginHost loads the QuickTime bundle and calls a function that generates this file. If the file does exist, we read it directly for MIME type information. I'm not sure who's responsibility it is to regenerate this file if it's stale.

Scanning all installed components to see what MIME types they handle is fairly expensive so the plug-in doesn't do it on startup. I believe the QuickTime installer forces the file to be regenerated when a new version of QuickTime is installed.
