Sorry I don't know much about what European weather information is
available. From what I've heard it's harder to come by than the weather
data provided by the United States National Weather Service. Either way,
AWeather currently only supports United States radars :/

Well, I've fixed _a_ segfault :)

I'm not 100% sure if it's the same bug you're seeing so I've attached a
patch that may correct the problem. If you could try testing it, I would
appreciate it. I can build an updated .deb tomorrow if you would prefer
testing it that way.

It seems your computer is having trouble downloading and saving the data
files though. The status in the error log corresponds to an I/O Error,
I'm not sure what would be causing that, but it doesn't seem related to
AWeather.
