hi! the workaround for this problem.
it's some kind of strange bug. i have radeon hd 5670 and unity crashed for me too.

1. chceck if your card is still supported in ati closed driver for linux - they do not support 2xxx - 4xxx models in new drivers, so you need to install legacy drivers.

2 if that does not apply to you, do this:
- switch back to open drivers
- open terminal and do commands:

sudo apt-get install linux-source
sudo apt-get install linux-headers-3.5.0-17-generic

- switch back to closed ati drivers in your software center / software sources / additional drivers
- restart computer
at this point everything should be working just fine. it worked for me. ati working at full speed with unity and it's so much faster.

then open terminal and do this:
sudo apt-get install linux-headers-generic

workaround found on polish ubuntu forums. thank you!
