The autobuild test system (on sn-devel-144) has detected an intermittent failing test in 
the current master tree.

The autobuild log of the failure is available here:

The failure seems to be in the "samba" suite, whose build logs are available here:
The top commit at the time of the failure was:

    join: Remove unnecessary clone_only flag
    For the clone-only case, we have been avoiding a block of code in the
    DCJoinContext's __init__(). The main reason we do this is because the
    netbios_name is None for clones, and this block of code tries to derive
    a bunch of values based on the netbios_name (otherwise, a few lines into
    this block, it tries to do NoneType.lower(), which Python doesn't like
    very much).
    This code is not particularly clone-specific - it is just never going to
    work if the netbios_name is None. So we can change the conditional
    check, which allows us to get rid of the clone_only flag.
