NullPointerException using Proguard and SlidingMenu

NullPointerException using Proguard and SlidingMenu

I have a NPE that's only occurring when I obfuscate my code with Proguard,
hoping somebody can help. I have a quite complicated project that uses
ActionBarSherlock, SlidingMenu, Facebook, Google Play Services, Nine Old
Androids, Simple Crop Image, ViewPagerIndicator, Volley, and
WindowedSeekBar.
It appears to be choking on some code related to SlidingMenu. Here's the
mapped stack trace:

And here is my code that is crashing:
public class DualSlidingMenu extends SlidingMenu
{
private static final float SLIDING_MENU_FADE_DEGREE = 0.35f;
private Activity mActivity;
public DualSlidingMenu(Activity activity)
{
super(activity);
mActivity = activity;
setMode(SlidingMenu.LEFT_RIGHT);
setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
setShadowWidthRes(R.dimen.sliding_menu_shadow_width);
setBehindOffsetRes(R.dimen.sliding_menu_offset);
setFadeDegree(SLIDING_MENU_FADE_DEGREE);
setFadeEnabled(true);
attachToActivity(activity, SlidingMenu.SLIDING_CONTENT);
setMenu(R.layout.view_menu_content_frame);
setSecondaryMenu(R.layout.view_matches_content_frame);
}
}
