Suddenly - no Nautilus!

[Amichai Rotman]

Hi All,

I am not sure how I did this - but I am no longer able to open a Nautilus
window. When I try to access a folder, the window opens and immediately
closes.

It has to do with a recent upgrade, after adding a PPA.

If  try to run it from a console, I get a lot of output. I won't paste it
all here, but the last few lines:

  File "/usr/share/nautilus-python/extensions/arista-nautilus.py", line 38,
in <module>
    import nautilus
ImportError: No module named nautilus
0x0000000000000000-DEBUG [x] Agent connection is dead, re-connecting
0x0000000000000000-DEBUG [x] Failed to connect Error 66: Socket connect
error
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)

There is more, but I need one of you to remind me how to use pastebin for
the rest...

Any ideas how to fix this? How to find out how it happened?

Let me know if you need more information.

Thanks!

Amichai.
