Comment 0 for bug 851932

Possibly related to #672884.

I've discovered this issue, when Nautilus suddenly became completely unresponsive, preventing me from browsing the filesystem with it. After a bit of poking around and checking UbuntuOne Control Panel, the latter gave me that error: "DBusException: org.freedesktop.DBus.Error.NoReply: Did not receive a reply." in bold red in the window under both file sync and shared directory list tabs. As I had some pending file changes, it was obviously also trying to update the files, which was also constantly failing. The logs are given below.

Uninstalling ubuntuone-client-gnome helped me get back Nautilus to work, so that package is obviously related. Still, control panel reports the same error and I'm still getting the same exceptions in the syndaemon-exceptions.log.

Here's my ~/.cache/ubuntuone/log/syncdaemon.log:

I also have some seemingly strange behavior in controlpanel.log:

This is what it looks when I called

$ cat syncdaemon-exceptions.log*

      $ rm -rf '~/Ubuntu One'

didn't help to solve the issue.

That last log's exception sure looks like a bug to me and might as well be the culprit of the nautilus misbehavior
