In normal operation, Phone.getLine1Number() returns an empty string if the device doesn't know its own phone number for some reason. However the monkey caught a case where it was returning null, which crashed the Settings -> About Phone -> Status app. However the javadoc for Phone.getLine1Number() *does* clearly say "May return null if not available or the SIM is not ready", so the Status app *should* gracefully handle this. Now it does. (We display this case as "Unknown", just like if we get an empty string.) FWIW I grepped thru the rest of the code base for other uses of getLine1Number(), and everybody else *does* handle null gracefully except for one case in apps/Mms, which I'll open a separate bug about.
