NextGEN Gallery Deprecated Call

My NextGEN Gallery plugin as well as WordPress are both up to date.

I’m getting an error about the following deprecated call coming from NextGEN Gallery:

Incorrect Use of register_uninstall_hook()
Used in wp-content/plugins/nextgen-gallery/nggallery.php on line 79.

Only a static class method or function can be used in an uninstall hook.
This message was added in version 3.1.
