Desktop icons and open windows disappear when opening windows share

[ubducted]

On Ubuntu 9.04 when I click on my Places>bookmarks to open my windows share (smb://192.168.etc...), all of my open windows (nautilus, firefox, gimp, anything) will disappear along with my desktop icons.

I can open up new windows, even for those programs that disappeared. (firefox, nautilus, etc.).

The problem seems similar to this thread: http://ubuntuforums.org/showthread.p...dows+disappear

However, my programs are not crashing. PS command still shows they are running.

I've also tried this solution, but it didn't help: http://ubuntuforums.org/showpost.php...06&postcount=6

This only happens when I browse to a windows share.

Please help!

I spoke to soon.

Nautilus IS crashing. And it's only Nautilus and my desktop icons that are now disappearing.

When I run Nautilus, it runs with the --no-desktop option.

I should also mention that I can browse media like external USB drives.

Also, I just tested connecting to an FTP server. That also crashes Nautilus.

GNOME Commander browses these filesystems without problem.

There is also no longer a context menu when right clicking on the desktop.

Compiz is not installed.

Well, I've learned more about the problem:

$nautilus 2> error.txt
Initializing nautilus-image-converter extension
Initializing nautilus-clamscan extension
Initializing nautilus-open-terminal extension
Segmentation fault
$

The error.txt reads:

Nautilus-Share-Message: Called "net usershare info" but it failed: 'net usershare' returned error 255: net usershare: cannot open usershare directory /var/lib/samba/usershares. Error No such file or directory
Please ask your system administrator to enable user sharing.

There are plenty of threads and a bug report about the problem, but I haven't found any solution.
