Runtime error while usb debugging Android

Question

I am learning how to build android apps, this is an app that I am working on as I go through the developer training. The app has been running fine on my android until I tried to add the action bar. Now the app crashes each time I try to start it. There seem to be no errors in my java source file.

Log Cat gives me theses errors:

04-30 18:17:28.268: E/Trace(19822): error opening trace file: No such file or directory (2)

.....

I have uninstalled and re-installed the app onto my phone with no difference. All of my drawable files are in the res/ directory.

Here is the source code for the action bar:

/* this method is the onCreate for the action buttons in the actionbar */
@Override
public boolean onCreateOptionsMenu(Menu menu) {

    // this MenuInflater object inflates menu items for use in action bar
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main_activity_actions, menu);

    return super.onCreateOptionsMenu(menu);
}
