URLError in weather applet

[onox]

Just found this in the output of avant-window-navigator:

Weather Applet: Unexpected error while fetching conditions:
Traceback (most recent call last):
  File "/usr/share/avant-window-navigator/applets/weather/weather.py", line 351, in fetchConditions

Hmm, with only this information this just seems like an http timeout, nothing particularly strange, unless it is happening constantly. Requests can time out due to a problem with weather.com or the local network. Does it have any negative effect on the applet? I would expect the next update to grab the weather again.

It doesn't happen constantly, and I don't know what consequences it has, maybe just that it cannot show the new data. But you should still catch this exception and do something with it. I think you should just ignore it, but if it happens 'multiple times' / constantly, then display an error.

If you do decide to display an error after multiple occurrences of this
error please do it through libnotify. Applets that bring up annoying
dialogs (mail in the past did this) caused by network errors are a bad idea
IMO.

When I waked up this morning I saw these errors:

[Michael Rooney (mrooney)]

These look like problems with your network connection or other random
issues. I could catch them but I am not sure there is a point; I think the
update silently failing is normal behavior in this case. Perhaps adding a
libnotify message if the update fails twice in a row could be nice. What
exactly do you want to happen?

Fixed in revision 1873. A notification will be shown if an error occurs.
