Hmmm, I am still experiencing this with plasma-widgets-addons
4:4.4.2-0rc1. Did Fedora developers apply some patch? Could you have a
peek in the package changelog?
plasma-widget-yawp might be an alternative, but it needs a recompile and I
wonder about libweather-ion4 which seems to be a part of kdebase-workspace
source package but is not compiled for KDE 4.4.2 packages. Has it been
dropped upstream?
