NoClassDefFoundError when using proguard

My Project contains some librarys (ViewPagerIndicator, ActionbarSherlock, SlidingMenu...). After using proguard, my application crash every time when starts. Below is error log

java.lang.NoClassDefFoundError:android.support.v4.appp.FragmentActivity$2 at android.support.v4.app.FragmentActivity.<init> (Unknown Source)....

And here is my proguard script:

    -injars      bin/classes
-injars      libs
-outjars     bin/classes-processed.jar

-dontpreverify
-repackageclasses ''
-allowaccessmodification
-optimizations !code/simplification/arithmetic
-keepattributes *Annotation*
-verbose

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.support.v4.app.FragmentActivity
-keep public class * extends android.support.v4.app.Fragment

-keep public class * extends android.view.View {
    public <init>(android.content.Context);
    public <init>(android.content.Context, android.util.AttributeSet);
    public <init>(android.content.Context, android.util.AttributeSet, int);
    public void set*(...);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.content.Context {
   public void *(android.view.View);
   public void *(android.view.MenuItem);
}

-keepclassmembers class * implements android.os.Parcelable {
    static android.os.Parcelable$Creator CREATOR;
}

-keepclassmembers class **.R$* {
    public static <fields>;
}



-dontwarn android.support.**
-dontwarn com.google.android.maps.**

Rather than being as specific with the package names

-keep public class * extends android.support.v4.app.FragmentActivity
-keep public class * extends android.support.v4.app.Fragment

Change it to this:

-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }

In the error it is looking for (note the extra p): 

android.support.v4.appp.FragmentActivity$2

rather than just 

android.support.v4.app.FragmentActivity.<init>

Edit, not sure what it could be, here's a full proguard for one of my apps that uses the support library and ActionBarSherlock.
