app force closes when selecting WAUS-FM from "Local Stations", station search, etc.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Tap Stations
2. Tap 'Call sign or zip code'
3. Enter 'waus'
4. Tap 'Search!'
5. Tap 'WAUS-FM - 90.7 FM, Berrien Springs'

At this point, the app force closes.

I am using version 1.2.1, version code 3 of the NPR app on Android 1.5 
(MotoBLUR) on a Motorola Backflip.

adb reports the backtrace below.  I started to look into this, but a) the 
downloadable source doesn't appear to match my .apk, and b) it wasn't 
immediately obvious how to build said source (I've not done Android 
development, maybe it's just ignorance).  I'll look more deeply when I get a 
chance.

This particular station has no streams or podcasts so there is no "first" group 
to be expanded.  I've proposed a fix that displays zero counts when there are 
no streams or podcasts and attached the modified source file.
