Comment 4 for bug 1289318

If it helps there is this in dmesg:

[ 86.177156] samba-tool[1643]: segfault at 0 ip (null) sp 00007fff780ce138 error 14 in python2.7[400000+2bd000]

this is after login as normal user, changing to root via 'sudo su' and running 'samba-tool domain exportkeytab /etc/krb5.keytab'

the response on the command line is: Segmentation fault (core dumped)

You only get this response, if you run the command as root, if you run it as a normal user, you get no response.

As I said, this was a known problem with the debian 4.1.3 package and it went away with the debian 4.1.4 package.
