Occasional NullPointerException in SavedState.writeToParcel

Created by: alwaysthecritic

We're seeing occasional crashes in the field (thanks Crashlytics) in writeToParcel(). I don't have a local repro for this.

com.sothree.slidinguppanel.SlidingUpPanelLayout$SavedState.writeToParcel (SlidingUpPanelLayout.java:1504)
android.os.Parcel.writeParcelable (Parcel.java:1292)

The line of code in question is:

out.writeString(mSlideState.toString());

Presumably mSlideState is null for some reason. Perhaps someone very familiar with the code might see how this could happen? I'm not in a good position to "thought-debug" it unfortunately.
