mutter hangs the desktop refresh

[Narayanan N]

Binary package hint: mutter

Just after today's update, I am no longer able to use the unity interface to login. I only get a blank screen after logging in.
When I logged into gnome session and started mutter, no more X events were handled neither the display got refreshed. I even tried to open some programs from the console by typing xterm, firefox, gv etc. All these were executed, but no change in the display screen. Only mouse pointer can be seen moving.

Later I tried to use gdb. But there is no crash of mutter whatever I tried. When I started unity (unity -s or unity -p) from terminal after mutter was started, I could see the mouse pointer change to I if I open a terminal or back to default if I move it away. Then if i used the mouse to click at some random places, it ends up in a crash of unity.

I am reporting bugs of unity as well as mutter. I have a gdb trace of unity crash.
