Bug Description
After restarting compiz with the "compiz --replace" command, attempting to switch workspaces will cause the display to freeze. The only way to recover (aside from rebooting) is to restart the X session with Ctrl+Alt+PrtScrn+K, but the problem usually (though not 100% of the time) persists after this.
When compiz is started normally at logon, this problem does not occur, but restarting compiz with 'compiz --replace' causes this bug to occur when switching workspaces. I'm not sure if this is because doing this makes it so that compiz has no parent or child processes.
Steps to reproduce:
(compiz is running at this point)
1. Hit Alt+F2 (Run Application) and enter "compiz --replace"
2. Attempt to switch workspaces (Ctrl+Alt+
((EDIT: This MIGHT be a duplicate of bug 711378. My theory is that perhaps this bug causes my workspace switcher applet on gnome-panel to get messed up; however, I don't see how that applet failing could possibly cause my entire screen to freeze and require a restart of X, so it's PROBABLY a different issue. But, unlike in that bug, I CAN see gnome-panel after restarting compiz perfectly fine,))
My specific setup was 2 workspaces beside each other (horizontal virutal size = 2, vertical cirutal size = 1, number of desktops = 1). The desktop wall plugin is turned on, but no other plugins under the Desktop category are turned on.
This bug report was submitted after rebooting from a freeze as a result of this bug, so any uploaded logs that only store information about errors occurring since the last reboot will not show the bug occurring. If it would help, I could cause this bug to occur, Ctrl+Alt+PrntScrn+K out of it, and attach the necessary files.
I am using GNOME Classic.
One interesting thing I noticed was that after attempting to figure out the exact conditions of this bug, I had restarted the X session (Ctrl+Alt+

I should also mention that it is NOT necessary to be running compiz when entering "compiz --replace".
Switching from Compiz to Metacity then back to Compiz also produces this error.
