wesj told me he ran into this while testing his Twitter panel last week, but I haven't seen a bug filed on it. Looks like fallout from bug 976064. E/GeckoAppShell( 7074): java.lang.NullPointerException E/GeckoAppShell( 7074): at org.mozilla.gecko.home.DynamicPanel$PanelDatasetLoader.loadCursor(DynamicPanel.java:417) E/GeckoAppShell( 7074): at org.mozilla.gecko.home.SimpleCursorLoader.loadInBackground(SimpleCursorLoader.java:44) E/GeckoAppShell( 7074): at org.mozilla.gecko.home.SimpleCursorLoader.loadInBackground(SimpleCursorLoader.java:26) E/GeckoAppShell( 7074): at android.support.v4.content.AsyncTaskLoader.onLoadInBackground(AsyncTaskLoader.java:242) E/GeckoAppShell( 7074): at android.support.v4.content.AsyncTaskLoader$LoadTask.doInBackground(AsyncTaskLoader.java:51) E/GeckoAppShell( 7074): at android.support.v4.content.AsyncTaskLoader$LoadTask.doInBackground(AsyncTaskLoader.java:40) E/GeckoAppShell( 7074): at android.support.v4.content.ModernAsyncTask$2.call(ModernAsyncTask.java:123) E/GeckoAppShell( 7074): at java.util.concurrent.FutureTask.run(FutureTask.java:234) E/GeckoAppShell( 7074): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1080) E/GeckoAppShell( 7074): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:573) E/GeckoAppShell( 7074): at java.lang.Thread.run(Thread.java:841)

Oops, this was filed as bug 995420.
