Freeze break request for mutter

[Rui Tiago Cação Matos <tiagomatos gmail com>]

Hi,

Pavel Vasin has filed patches to plug several memory leaks in mutter
found with valgrind[1].

At least 2 of those patches[2] fix serious memory leaks since those
code paths are often taken (especially the 1st one).

Is it OK to commit those 2 patches?

Thanks,
Rui
