Tab activity seeming to die randomly loading state drawable

I have a TabActivity that seems to be dieing on a small set of phones when I add the Drawable to it. From the reports, the same tab code ran successfully at one point, but suddenly stopped during one launch(usually via pending intent)

The code thats executing in onCreate is this

spec = theTtabHost.newTabSpec(STATS_TAG).setIndicator(getText(R.string.statsTab),
            res.getDrawable(R.drawable.ic_tab_stats))

The stack trace I receive is here

The ic_tab_stats.xml file is in drawable, and is here.

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/stats"
          android:state_selected="true" />
    <item android:drawable="@drawable/stats_deselect" />
</selector>

The stats.png and stats_deselect.png are peers inside drawable. hdpi and ldpi do not have either file, and mdpi is empty. My app supports back to 1.5, so I used drawable instead of md开发者_如何转开发pi.

From the reports, it seems to be pretty random.

Turns out this is sort of normal behavior on Android upgrades.
