[Bug 1723822] Re: uncaught TypeError triggers ValueError

[Brian Murray]

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.
