nautilus crashed with SIGSEGV in g_file_query_info()

[Doug McMahon]

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

This was apparently due to deja-dup's nautilus plugin using some glib functions during nautilus initialization. By delaying deja-dup's own initialization until nautilus is done, we avoid the crash. I fixed it upstream, will shortly push a patch in Ubuntu.

This bug was fixed in the package deja-dup - 19.4-0ubuntu2

deja-dup (19.4-0ubuntu2) oneiric; urgency=low
