Subject: [PATCH] print-notifications: detect malformed d-bus signals

Fixes a crash that happens when receiving a d-bus call with an invalid
number of arguments.  The issue was first reported at lp #893676.  A
patch to CUPS which makes it stop sending those malformed signals has
been submitted to cups.org as STR #3984. (#665689)
