Weather Indicator should clear up corrupted DB

Binary package hint: indicator-weather

I installed indicator-weather today.
After starting it and choosing my settings, it hanged during confirmation; so I terminated the program.
I made some retries, with no success. Now the program does not start.

Traceback from terminal:
