cygwin 1.7.0-40: Socket operation on non-socket

[Steffen Sledz]

On one of my machines running cygwin a few programs (like rsync or dig) fail with an error like this (for detailed info see attached strace.txt):

 $ dig @dns1.dresearch.de www.cygwin.com
 /usr/src/ports/net/bind/bind-9.6.0-1/src/bind-9.6.0/lib/isc/unix/socket.c:4525: bind: Socket operation on non-socket
 dig: isc_socket_bind: unexpected error

A search in the mailing lists results in some hits with similar problems, but none of them seems to be resolved really satisfactorily (often the answer was just "works for me"):

One hint could be that there is Panda for Desktops running on this system. I'm not able to disable this because of domain policy rules. But i can't believe that this is really the problem. On a second system running the same cygwin and Panda versions (with exactly the same configuration) everything works well.
