 Uninstall does not work with Callbacks:

 When a Plugin registers an uninstall hook (using API call
 register_uninstall_hook()) with an instance of a class, deleting a
 deactivated plugin will fail later on.

 When the deletion process is triggered (uninstall_plugin($plugin)),
 get_option('uninstall_plugins') will return callback values. I assume that
 because the plugin isn't included any longer because of being deactivated,
 get_option returns (automatically de-serialzed) objects of type
 '''__PHP_Incomplete_Class''' instead of '''aConcretePluginClass'''.
 Therefore the uninstall callback fails then.

 A first workaround suggestion is to use the uninstall.php file instead of
 an uninstall hook.
