It seems that you haven't restarted the X server between running your apt commands and getting the crash. That won't work; the running X server is still using fglrx's GLX, which is (as you have found) incompatible with mesa.
Also, that's not the supported way of switching to the free drivers; the Additional Drivers tab of Software Sources is the supported method. What you did should work, though, after a reboot.
