I also get this in my frontend log and the lcd server has suddenly stopped
starting up.
 ASSERT: "i <= nodes" in /usr/qt/3/include/qvaluelist.h (373)
The problem goes away if I start the lcd server manually and then the
frontend. Maybe unrelated, but until I do this, mythweather fails as well
(blank screen) - weird or what...
