nautilus crashed with SIGSEGV in g_file_query_info()

This crash occurs when trying to run a root nautilus and has been reported. The issue here and on other installs of mine is caused by the deja-dup package being installed
As soon as it is removed I can open a root nautilus browser from terminal or run dialog.

Please note that on this fresh install if deja-dup is re-installed I can no longer open a root nautilus. (same crash occurs
However on an older install I can re-install deja-dup, though I'd need to ck. to see if I disabled it from autostart
