I'm experiencing this bug as well, it seems. I'm attaching the output of gdb after attaching to compiz (which is what hangs/freezes).
This bug happens when a new window wants to open. That's my experience at least. It can be any window. A new dialog in an existing program, or a new program opening up a window (for example mplayer).
This happens for me using mesa from git from this PPA: https://launchpad.net/~oibaf/+archive/graphics-drivers/
I'm on r600g and x86-64 as well.
