[Sébastien Bernard]

Public bug reported:

Binary package hint: krb5-user

Updated today a new version of kerberos 5 on the developpement distribution.
This version crash a every sollicitation witch a SIGSEGV.
This makes the user unable to log. I had to switch to ldap before being able to get into the system.
The machine is authenticating againt a 1.6.dfsg.4~beta1-5ubuntu2.2 kdc.

To reproduce is easy, just launch kinit and you get a sigsegv in return.
Here's the trace under gdb:
