My-weather-indicator 0.4.x (including 0.4.1.5) doesn't work at all on Ubuntu 10.04 "Lucid" - always crashes :(

My-weather-indicator 0.4.x (including latest 0.4.1.5) doesn't work at all on Ubuntu 10.04 "Lucid" - always crashes after I choose locations in preferences dialog :(
It seems problem is in compatibility with older appindicator, because I get an error AttributeError: 'appindicator.Indicator' object has no attribute 'set_label' in terminal, here is full terminal output:
