    retitle 265402 Tk aborts on exit when talking to X through PF_UNIX socket thanks

    Ok, this is interesting, but somewhat overstated. It does not abort
    when $DISPLAY is set to something other than ":0" (which would be a
    major bug). I set $DISPLAY to point to my FreeBSD box, and that
    worked fine. So it seems that it's just the use of Unix-style
    sockets, rather than the more usual IP sockets, that triggers this.
    Using Unix-style sockets for X is pretty obscure - I don't think I've
    seen anyone even try before.

    Furthermore, it only aborts on exit, as far as I can tell. I ran
    tkdesk with $DISPLAY pointing to a unix socket, and it seemed to work
    perfectly until I exited, at which point it produced the same error
    message. So it looks pretty harmless.

    But for all that it seems to be both obscure and essentially harmless,
    I can't deny that it looks like a bug, so I'll investigate further
    when I get some time. Thanks for calling this to my attention.

    cheers
