Bug 191246

Description of problem:
The cupsd segfaults after I connect to it using an Internet browser and provide
it my authentication credentials.  My system uses Kerberos for authentication
and LDAP for network information.

Version-Release number of selected component (if applicable):
cups-1.1.23-30.2
pam-0.99.3.0-2

How reproducible:
Every time

Steps to Reproduce:
1.  Install cups-debuginfo and pam-debuginfo.
2.  Ensure cupsd is not running
3.  gdb cupsd
4.  gdb> run -f
5.  Use a Internet browser to connect to cups (i.e.: http://localhost:631)
6.  Select "Do Administration Tasks" and authenticate
  
Actual results:
Cups crashes with the following backtrace:
