I just installed Nautilus Columns (Nautilus extension) in Ubuntu 12.04 64bit and after installing it I can't open Nautilus it just Crashes/Closes when I try opening it.

This is the message I get from the command line when I run Nautilus :

Initializing nautilus-ideviceinfo extension
/usr/lib/python2.7/dist-packages/gobject/ Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed
import gobject._gobject
Traceback (most recent call last):
File "/usr/share/nautilus-python/extensions/", line 38, in
import nautilus
ImportError: No module named nautilus
Initializing nautilus-dropbox 0.7.1
TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases
Segmentation fault (core dumped)

Does anyone have any ideas because I would like to get this working.

After a suggestion from another user named Andrew he suggested I uninstall Arista due to something in the output in the command I posted and the Nautilus and Nautilus-Columns worked fine together. I also reinstalled Arista and didn't get anymore crashes with Nautilus as well
