I have the same problem with zombie process. Each time I close the Date & Time preferences dialogue I end up with the process blocking the subsequent opening of Date & Time preferences.
$ ps ax | grep indicator-datetime-preferences 2007 ? Sl 0:00 indicator-datetime-preferences I have to kill that process whenever I need to launch Date & Time preferences, otherwise it fails with the message (indicator-datetime-preferences:5032): Unique-DBus-WARNING **: Error while sending message: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. The important thing is, that I only get this problem when using clock applet Date and Time preferences. If I use Unity launcher or the terminal, everything is working fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751175 Title: Time and Date Settings don't load (Natty Beta 1) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
