Things like that usually happen around when PyQt4 start changing versions/getting updated into Devel. They tend to get fixed within a day or two.

Since pyRadio isn't yet in testing I'm not really sure how to have you try and work around it. Possibly making sure you install python-qt4 or python-qt4-gui before enabling devel and grabbing it.

I've been debating lately whether to push it forward.. but I'm not sure it's really stable enough (especially on poor connections) to really be "extras" worthy yet.
