Bug#634937: cups: Seen this in my messages log

["Andrew Worsley <andrew.worsley>" <amworsley@gmail.com>]

Package: cups
Version: 1.5.3-5+deb7u1
Followup-For: Bug #634937

Dear Maintainer,

  I wasn't doing anything particular and noticed that the cups daemon was no longer running when a print job failed
  to appear. I grep'ed the messages log and got this single line:

   grep cups /var/log/messages.1
Jan 25 11:53:28 azza kernel: [3067672.112302] cupsd[17528]: segfault at 220 ip 00007ffbffc0c1b3 sp 00007fff5544e818
error 4 in libavahi-common.so.3.5.3[7ffbffc07000+c000]

  Restarting cupsd via 
    service cups restart

  starts printing happening again. But the print job needed to be re-submitted.
