Comment 50 for bug 293970

Similar problem here, this could be related:

the socket in /tmp is never created for me, despite this:
harald@belial:~$ strace dbus-daemon --session --print-address
[..]
socket(PF_FILE, SOCK_STREAM, 0) = 3
bind(3, {sa_family=AF_FILE, path=@"/tmp/dbus-CMm700Tb5o"}, 23) = 0
listen(3, 30) = 0
fcntl(3, F_GETFL) = 0x2 (flags O_RDWR)
fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
fcntl(3, F_GETFD) = 0
fcntl(3, F_SETFD, FD_CLOEXEC) = 0
[..] (no further calls to fd 3)
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=5, events=POLLIN}], 3, -1 <unfinished ...>

during this, no /tmp/dbus- file is created ...
$ ls -l /tmp/dbus-*
   ls: cannot access /tmp/dbus-*: No such file or directory
