Comment 2 for bug 1723822

There are two issues here, one with apport and another with nautilus. The nautilus package ships an apport-package hook and it is looking for information about plugins in /usr/lib/nautilus which is not where they are stored anymore.

 12 # collect informations on the /usr/lib/nautilus components
 13 plugin_packages = set()
 14 for dirpath, dirnames, filenames in os.walk("/usr/lib/nautilus"):
 15 for filename in filenames:
 16 path = os.path.join(dirpath, filename)
 17 package = apport.packaging.get_file_package(path)
 18 if package == 'nautilus':
 19 continue

 $ ls /usr/lib/nautilus/
ls: cannot access '/usr/lib/nautilus/': No such file or directory

I think they've moved to /usr/lib/x86_64-linux-gnu/nautilus/extensions-3.0. Regardless, the apport package hook from nautilus needs updating.
