Public bug reported:
Binary package hint: samba
When trying to login using GDM, XDM or KDM, there is a segfault in
libtalloc, when called by pam_smbpass, see attached log for stacktrace.
Since libtalloc2 works fine for the other software that uses it, I guess it's
pam_smbpass's fault.
Also, it works fine when logging in on the console.
libpam-smbpass Version: 2:3.5.1~dfsg-1
libtalloc2 Version: 2.0.1-1
