Error starting conversation list activity from broadcast receiver on deveice

Question

I've got a broadcast receiver that gets triggered when a notification my app created is clicked. When that broadcast receiver is started it completes a task then tries to bring of the sms conversations. It works fine on the emulator, however when I try it on a droid incredible it crashes with the following message

07-07 22:57:23.901: WARN/ActivityManager(81): Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.android.mms/.ui.ConversationList } from ProcessRecord{460a37f8 6949:msc.test/10081} (pid=6949, uid=10081) requires null

The code just looks like the following

 public void onReceive(Context _context, Intent _intent)
     {
// do stuff

 try
         {
             Intent intent = new Intent(Intent.ACTION_MAIN);
             intent.addCategory(Intent.CATEGORY_LAUNCHER);
             intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK );
             intent.setClassName("com.android.mms", "com.android.mms.ui.ConversationList");
             _context.startActivity(intent);
         }
         catch(ActivityNotFoundException e)
         {
            //handle except
         }
}
