This showed up at some point in the past during our own
internal CTS testing but it seems wrong based on the DAC
permissions and a potential way to inject code into apps
from the shell.  Drop it for now and see if it shows up again.
This predates userdebug/eng vs user shell split so possibly
it only happens in the userdebug/eng case.
