Can't lock X with xscreensaver

[Robert Arkiletian]

This is with F9 but Peter S. also reports F10 fails too.

Before I ran this I killed gnome-screensaver first.

[rob at server ~]$ xscreensaver &
[1] 3623
[rob at server ~]$ xscreensaver-command -lock
xscreensaver-command: activating and locking.

    If at all possible, please re-run xscreensaver with the command
    line arguments `-sync -verbose -log log.txt', and reproduce this
    bug.  That will cause xscreensaver to dump a `core' file to the
    current directory.  Please include the stack trace from that core
    file in your bug report.  *DO NOT* mail the core file itself!  That
    won't work.  A "log.txt" file will also be written.  Please *do*
    include the complete "log.txt" file with your bug report.

    http://www.jwz.org/xscreensaver/bugs.html explains how to create
    the most useful bug reports, and how to examine core files.

    The more information you can provide, the better.  But please
    report this bug, regardless!
