Package: cups
Version: 1.4.4-7

If I try to carry out an action in the web interface that requires
authentication, e.g. pause the printer, cupsd daemon crashes:

I suspect this might have something to do with PAM LDAP. It works fine if I:

* authenticate as root instead of an LDAP user.

However still fails if I:

* disable TLS for LDAP NSS module.
* disable TLS for LDAP PAM module.
* Configure cups to use http instead of https.

So doesn't appear to be a TLS library issue.

Dear Debian User,
                                                                                                     
This bug report was submitted against a version of CUPS that is no longer
supported in Debian. Use of our limited, volunteer supported resources is best
served by not keeping around old, hardware-specific and inactive bugs for
longer than desirable, so the report is now being closed. Sorry for being
unable not to address the issue before now.

You may, of course, wish to review the reported problem. It would be
appreciated if any future investigation could be conducted using the testing or
unstable distributions, preferably the latter. If considered necessary, a new
bug report, possibly referencing this one, would be submitted. 

Thank you for your report.                                                        
                                                                                                                      
Regards,
