[Pkg-samba-maint] Bug#484235: Bug#484235: panic-action called for /usr/sbin/winbindd

[Jim Barber]

Hi.

I've upgraded to the new version and also installed the samba-dbg package this time.
No changes were made to the Samba configuration.
The LDAP libraries were also updated.
I still experience crashes.

The versions of packages that have changed since the previous list are as follows:

ii  libldap-2.4-2               2.4.9-1                     OpenLDAP libraries
ii  samba                       2:3.0.30-2                  a LanManager-like file and printer server for Unix
ii  samba-common                2:3.0.30-2                  Samba common files used by both the server and the client
ii  samba-dbg                   2:3.0.30-2                  Samba debugging symbols
ii  samba-doc                   2:3.0.30-2                  Samba documentation
ii  winbind                     2:3.0.30-2                  service to resolve user and group information from Windows NT servers

The panic dump is as follows:

	The program is running.  Quit anyway (and detach it)? (y or n) [answered Y; input not from terminal]
