Question

i had the same problem and have just found out, that if you change your preferences to:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
 <PreferenceCategory android:title="@string/pref_cat_general">
 </PreferenceCategory>
  <PreferenceScreen android:key="@string/pref_cat_scr_keygen" android:title="@string/pref_cat_scr_keygen_title" android:summary="@string/pref_cat_scr_keygen_summary">
   <intent android:action="android.intent.action.VIEW" android:targetPackage="com.android.clean" android:targetClass="com.android.clean.KeygenAct" />
  </PreferenceScreen>
</PreferenceScreen>

Then it works as expected. This is weird because I would expect PreferenceCategory to group items as its children... And why does it result with such unrelated (?) error?
