Description of problem:
Metacity goes into a loop, restarting over and over again.  This was apparently triggered by opening a firefox window with a very, very long title.

Version-Release number of selected component (if applicable):
2.11.0-3

How reproducible:
Didn't try

Steps to Reproduce:
1. Open a firefox window with a very, very long title.

  

Actual Results:  Every time I switched to the desktop with the firefox window, metacity restarted (well, crashed, and gnome-session restarted it).

Expected Results:  It should have not crashed.  Perhaps truncate the title?

... etc

I'm marking this "high" because, well, it's the window manager. Without it, it's hard to do anything ..
