Details

I just installed Pentadactyl[1] for testing and that opened some welcome page, namely "dactyl://help/intro". After removing the add-on again I had an entry on the new tab page for that and the background thumbnailer tried to load and capture that page:

System JS : ERROR chrome://global/content/backgroundPageThumbsContent.js:89 - NS_ERROR_UNKNOWN_PROTOCOL: Component returned failure code: 0x804b0012 (NS_ERROR_UNKNOWN_PROTOCOL) [nsIWebNavigation.loadURI]

We should guard against failures like that and abort the capture.
