[Bug 217787] [NEW] cups crashes when using web-gui and refuses to print

Binary package hint: cupsys

I tried to print today but the printing job was just put in the queue
and nothing was printed. I did not get the printer icon in the
notification area.

I noticed how I got errors in auth.log from cups:

Apr 15 15:42:56 thnov-desktop cupsd: PAM unable to dlopen(/lib/security/pam_smbpass.so)
Apr 15 15:42:56 thnov-desktop cupsd: PAM [error: /lib/security/pam_smbpass.so: cannot open shared object file: No such file or directory]

I found that in bug #216990 this was solved by installing libpam-
smbpass. Why was i missing this package?

Anyway, after I installed it, still I cannot print. I restarted cups via
'/etc/init.d/cupsys restart' and I can see that user lp has a couple of
processes which seems to be handling by printing jobs.

When I go to localhost:631 in a browser cups immediately crashes. This
crash is not picked up by apport nor is anything written in /var/crash.

I started the process manually so I could see the crash:

$ sudo /usr/sbin/cupsd -f
sh: /usr/share/samba/panic-action: Permission denied
Aborted (core dumped)

So, every time I restart cups now my jobs are being processed but
nothing is being printed. I see no activity at my printer. As soon as I
try to use the web gui it crashes.
