Android crash on Selecting ABS Item

For whatever reason, my ActionBar crashes when I click on one of its buttons. Here's the code for the optionsSelectMenu:

public boolean onOptionsItemSelected(MenuItem item)
{   
    switch (item.getItemId())
    {
    case R.id.refresh_button_actionbar:
        if (this.frag instanceof DashboardFragment)
            dashboardFrag.refresh();
        break;
    default: 
        return false;
    }
    return true;
}

And here is the logcat:

Any ideas of what I'm doing wrong? I'm thinking it has to do with the fragment comparison. Also, to note, when I just set the code to "return true" (as in it will do nothing but return true), it will re-start the activity. Is this intended behavior? If so, how can I get around it?

Here are my imports:

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;

import com.actifio.android.R;

import com.actionbarsherlock.app.ActionBar;
import com.actionbarsherlock.app.ActionBar.Tab;
import com.actionbarsherlock.app.ActionBar.TabListener;
import com.actionbarsherlock.app.SherlockFragmentActivity;
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuInflater;
import com.actionbarsherlock.view.MenuItem;

Solution

You are using Android's Menu and MenuInflater, but should be using the classes that come with ActionBarSherlock. Check if this is your import for them:

import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuInflater;

Check the answer given in this thread for a detailed explanation.Your problem should be solved. Next time make sure if this type of question is asked already.

EDIT:

I came up with a tweak(not very clean but works) to solve your problem. Hope you have the actionbarsharlock project in your workspace. Go to the package com.actionbarsharlock.app then locate the file SharlockFragmentActivity.java,open it up and go to line 201 (CMD/CTRL+L then enter the line number) now comment out the following lines:

try
        {
            if (BuildConfig.DEBUG) Log.d(TAG, "[onMenuItemSelected] featureId: " + featureId + ", item: " + item);
        }catch(Exception e)
        {
            Log.d(TAG,"Exception");
        }

Your problem should be fixed.
