Comment 11 for bug 1008184

It would be great if you could compile and install libmutter from git, I use it and it doesn't happen to me.
Installation:

$ sudo apt-get build-dep libmutter-dev
$ git clone git://git.gnome.org/mutter
$ cd mutter
$ ./autogen.sh
$ make
$ sudo make install

and then try to reprocude what caused the crashes earlier.
