Comment 8 for bug 833337

I'm experiencing this with indicator-datetime-0.3.1-0ubuntu1, from oneric-proposed with the following specifics:
My current location is listed twice consecutively in the indicator menu;
My current location is not defined in the locations dialog;
Defining my current location in the locations dialog has no effect;
When setting another location as "home" in the indicator menu, the extraneous home-location disappears;
When selecting the original home location in the indicator menu, the extraneous home-location reappears;
Defining additional locations with the same timezone as my home location and switching to and from them produces inconsistent, confusing results;

Reinstalling indicator-datetime and restarting is has no effect;
Installing all pending upgrades and rebooting did not help;
Running dpkg-reconfigure on tzdata does not help;

I was unable to find neither the settings file for the indicator my home directory nor any related entries in gconf.

What steps should i take to help resolve this issue?
