Yes, I guess so. Might also come out as empty string, if forced to be
converted to a string. As you can see from the code, though, it's only
valid/useful for certain status values, and for them it gives a
(translated) indication what happened. So normally, you should check the
status value, and in case of problems display the "message" string to
the user.
