Bug#1121751: cups-daemon: breaks printing in GNOME

[Lyndon Brown]

Ran into this myself today with firefox hanging as soon as I asked it
to print a pdf, and then evince did the same. Using gnome here. Noticed
that cups had been updated since I last printed something and found
that rolling it back to stable temporarily resolved it. (Though the top
portion of the document was duplicated, but that was probably just a
random printer failure; I seem to recall having experienced it once or
twice before).
