Same problem. Running pr1.3 and 0.1.5-1. Cannot start widget, it seems to crash all other widgets on the screen, everything disappears and default icons come back again.
Have uninstalled and reinstalled many times.

My upgrade from pr1.2 to pr1.3 was OTA so didnt have to reinstall if that made any difference. I like this widget so much am considering blowing everything away and doing a clean flash if necessary.
Hope I don't have to though.

Cheers
