Android preference activity does not update correctly

I created an android preference page and wanted to show the current option selected in the summary.

So I implemented the onSharedPreferenceChanged listener which is also called correctly. However, there is no screen change and the old option is shown. 

public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
    // just update all
    ListPreference lp = (ListPreference) findPreference(PREF_DOWNLOAD_WEB);
    lp.setSummary(getString(R.string.pref_listDownloadWebSummary)  + ": %s");
}

Is this a known bug?

I noticed that the updated summary is shown when I set another prefs summary. So I set the summary to "dummy" first and then the real string. It works too.

public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
    // just update all
    ListPreference lp = (ListPreference) findPreference(PREF_DOWNLOAD_WEB);
    lp.setSummary("dummy"); // required or will not update
    lp.setSummary(getString(R.string.pref_listDownloadWebSummary)  + ": %s");

}
