Okay, it looks like the DBUS_SESSION_BUS_ADDRESS is indeed valid bit python-dbus is unable to connect for some reason since ubuntuone- syncdaemon does not perform anything extra during the DBus connection.
Could those who encounter this issue try running the following line in the terminal, does it print any errors? python -c 'import dbus; print dbus.SessionBus()' ** Description changed: This bug reports serves as a master bug report for the issues caused by SyncDaemon not being able to contact the DBus server. If you are experiencing this issue please run the following in the terminal: - ps uxe | grep [u]buntuone-client - echo $DBUS_SESSION_BUS_ADDRESS + python -c 'import dbus; print dbus.SessionBus()' And post it as a comment. - Binary package hint: ubuntuone-client Traceback: org.freedesktop.DBus.Error.NoServer ProblemType: Crash Architecture: i386 Date: Thu Aug 27 20:13:33 2009 DistroRelease: Ubuntu 9.10 ExecutablePath: /usr/lib/ubuntuone-client/ubuntuone-syncdaemon InterpreterPath: /usr/bin/python2.6 Package: ubuntuone-client 0.93.1-0ubuntu1 PackageArchitecture: all ProcCmdline: /usr/bin/python /usr/lib/ubuntuone-client/ubuntuone-syncdaemon ProcEnviron: LANG=it_IT.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 2.6.31-8.28-generic PythonArgs: ['/usr/lib/ubuntuone-client/ubuntuone-syncdaemon'] SourcePackage: ubuntuone-client Title: ubuntuone-syncdaemon crashed with DBusException in __new__() Uname: Linux 2.6.31-8-generic i686 UserGroups: adm admin cdrom dialout lpadmin plugdev sambashare -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/420705 Title: ubuntuone-syncdaemon crashed with DBusException in __new__() -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
