I get this popup, but the list displayed is empty.  Of course, clicking Remove does nothing because there's nothing to remove.

I got this too... Tells me that it thinks something is wrong/bad, but no way to see what it's on about and no way to turn it off... Sometimes it says that an add-on has a bad reputation (for something I use regularly) but no way for me to "vote" or ignore.
