This is an upstream bug and has been fixed:
git commit 2012-05-01 meta_window_move_frame(): fix crash when frame is NULL

Looks like we need a newer libmutter.

This bug is in the main mutter code and has been fixed in git trunk

We have two choices here distribute our own mutter debs or wait until the code has reached ubuntu debs

I get this same crash when choosing a custom draw area for Eidete.

I was not using chrome and I got this crash message. In fact, I dodn't even notice anything wrong at all.

I get this when running office 2007 with playonlinux.

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

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

and then try to reprocude what caused the crashes earlier.

Fixed by cherrypicking the fix from upstream libmutter.
