Bug#327903: xdm server is not shown in chooser

[Tor Magnus Castberg <tmc@continually-evolving.net>]

Package: xdm
Version: 6.8.2.dfsg.1-6
Severity: important


When connecting to the xdm server with "X -indirect <servername>" the
chooser does not pick up the local xdm session. "X -query <servername>"
works fine. When using BROADCAST and other xdmcp servers are available,
the chooser will list these but not the local xdmcp server. When no other
xdmcp servers are available the chooser has one entry, "list", which will
cycle the xdm connection if selected. 

I suspect this is connected with the IPv6 issue where xdm
has broadcast problems if the interface is not listed with "LISTEN
<ip-address>" in Xaccess.

I get no error messages from xdm using -debug.

Issue is reproducible and has been tested on several machines.
