xorg log with brief backtrace

steps to reproduce:
- start x-server with glamor enabled
- start firefox

result:
firefox render blank window just after that x-server crashes

Unfortunately I was unable to generate good backtrace: I don't have another
machine to ssh, when I run with NoTrapSignals machine hangs and don't produce
crashdump.
