Comment 37 for bug 892370

I've figured out the immediate root cause, though I'm still puzzled why the new "clickanywhere" code causes the problem. The initialization path for the widget takes it through the function calls cc_timezone_map_init() and either 1 or 2 calls to cc_timezone_map_size_allocate(). Using the packages from the repo, there is no problem. When using the "clickanywhere" binary, there are some instances when cc_timezon_map_init() is not called _at all_! So when this happens, we SIGSEV. I'm not exactly sure why this is happening. The functions referenced above are automatically called somewhere out of gtk or glib, and there isn't anything in the code that I've written to indicate that the glue code shouldn't have to call cc_timezone_map_init()

Note that this is only a problem when using gnome_control_center. If you use "Time & Date Settings..." directly from the time dropdown in the indicator, there's no problem.
