[android-developers] java.lang.SecurityException: Requesting code from

Android4.0.3
Hi all,
         I wrote an android application, and sometimes  i got below issue while i use my application:
         ....
         E/AndroidRuntime(19081): Caused by: java.lang.SecurityException: Requesting code from com.android.local (with uid 10072)
         E/AndroidRuntime(19081):     at android.app.ActivityThread.getPackageInfo(ActivityThread.java:1582)
         E/AndroidRuntime(19081):     at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1852)
         E/AndroidRuntime(19081):     at android.app.ActivityThread.startActivityNow(ActivityThread.java:1797)
         E/AndroidRuntime(19081):     at android.app.LocalActivityManager.moveToState(LocalActivityManager.java:135)
         E/AndroidRuntime(19081):     at android.app.LocalActivityManager.startActivity(LocalActivityManager.java:347)
         E/AndroidRuntime(19081):     at com.chinamobile.cmi.jego.ui.activity.CallLogHomeActivity.onCreate(CallLogHomeActivity.java:93)
         E/AndroidRuntime(19081):     at android.app.Activity.performCreate(Activity.java:4465)
         E/AndroidRuntime(19081):     at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1049)
         E/AndroidRuntime(19081):     at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1920)

I checked my codes,  the issue is in CallLogHomeActivity.java (it's an ActivityGroup), and while we try to call activityManager.startActivity("0", intent).getDecorView(); above issue may appear, but the frequency of above exception is too low.
I got this exception 3 times. I just tracked the android SDK codes, and found that in the

performLaunchActivity function(ActivityThread.java), below module：
if (r.packageInfo == null)
{

            r.packageInfo = getPackageInfo(aInfo.applicationInfo, r.compatInfo,

                    Context.CONTEXT_INCLUDE_CODE)；

}

will active above exception. Anyone got the same issue, could you help me?
(all of activities are in one pacakage, there is no any out-package activities)
