A few lines down "ps" is run through a null check, so apparently there could be some screwy system conditions where this is encountered. And, in fact, this was encountered through an updated system pacakge that managed to delete the package from /system/app during testing. It left the PackageSetting in mDisabledSysPackages which would cause a deference of a null variable. Change-Id: Ic7faca569abd16a87a8a69c20df08c11a274a001
