How to reproduce

I don't know how to reproduce.
I just printed something and deleted some jobs from the print server queue, and then the printer applet crashes.

So the crash was from freeing the list of Connection objects, and it was
most likely caused by some kind of memory scribble.
The only thing I can see wrong in that code is that it assumes the to-
be-dealloc'd Connection object appears in the list. However, it ought
to.
Anyway, I can harden that (to protect against e.g. bit-errors) by only
removing the object from the list if it appears there in the first
place. Hopefully that will prevent this kind of problem.

I've discovered the reason for this, and have confirmed that the
upstream fix is correct.
First, a reproducer:
==>
import signal
import cups
def alarmclock (signum, frame):
raise KeyboardInterrupt
signal.signal (signal.SIGALRM, alarmclock)
connections = []
while True:
# Create
signal.alarm (10)
connections.append (cups.Connection ())
signal.alarm (0)
<==
This just keeps creating more and more connections until cupsd stops
accepting them (when it hits its maximum file descriptor count). At
that point, the program raises an exception and exits.
What happens is that Connection_init() fails *before* the newly-
allocated Connection object is added into the list. As the
initialization failed, the object is deallocated with
Connection_dealloc(), and of course that assumes the object is in the
list.
So the correct behaviour is to verify that the connection is in the list
before trying to remove it.
