Hey guys, so I was working on fixing an issue in RabbitVCS (a nautilus-python extension) where our context menu items were not getting refreshed like they used to be.  It used to be that you could right-click on a file, return a temporary empty list and in a separate thread generate a menu, then emit the "items-updated" signal and the menu would get refreshed without re-opening the menu.  Now, even with the items-updated signal getting passed, and get_file_items getting called again, the menu items don't change until I close and re-open the context menu.

I thought it might be due to a bug in nautilus-python, so I wrote up a C extension that reproduces the issue.

To reproduce, open nautilus and right-click on a file.  You should see an 'Always here' item.  Then, I would expect it to show a 'Sometimes here' item after a second but that doesn't happen.  If you close and re-open the menu you'll then see the 'Sometimes here' item.

This seems to be a regression because the "items-updated" signal mechanism is still in place, so I would expect it to refresh the menu items in an open context menu.
