Most of the significant things on earth happen to be accomplished by people who have kept on trying when there have also been no hope in any respect.
What is the subject of life – to have rich? All those fellows available getting rich could possibly be dancing around the real subject of life.

I get it in iPython as well. Some modules can be doctexted/searched successfully, but some cause a segmentation fault. So getting the error depends on which keyword you’re searching for and whether it occurs in the problematic modules.

Python 2.7.2+ (default, Oct 4 2011, 20:03:08)
Type “copyright”, “credits” or “license” for more information.

IPython 0.10.2 — An enhanced Interactive Python.
? -> Introduction and overview of IPython’s features.
%quickref -> Quick reference.
help -> Python’s own help system.
object? -> Details about ‘object’. ?object also works, ?? prints more.

I get a similar failure simply by doing this;

>>> help()

I have tried posting on the mailing list, but for some reason it fails all the time.

I have installed the latest RabbitVCS on three different computers running
Ubuntu 11.10 and I get this issue on all on them. From what I can see I do
not have any other Nautilus extensions installed on any of the computers. I
have checked for extensions in /usr/share/nautilus-python/extensions and
~/.local/share/nautilus-python/extensions (I don’t even have the last
folder).

The ~/.config/rabbitvcs/RabbitVCS.log file is empty.

Here are some output:

NAUTILUS_PYTHON_DEBUG=misc nautilus
** (nautilus:4999): DEBUG: SyncDaemon already running, initializing SyncdaemonDaemon object

Any ideas?

In reply to Evandro. Can you send this to the mailing list? This isn't a great place to help you. In your mailing list entry, please include the version of Nautilus you're running.

In reply to Adam Plumb.

Nothing is returned in this command.
See below. Any idea?
