firefox dbg backtrace

After the start of Firefox with WebGL enabled, it will crash, in my case my
firefox have a master password, my FF seems to crash when it show me the master
password window, if i cancel or put my password it will crash instantly.

actually i have updated Mesa from git, and i get the Firefox debug symbol,
as Mattwoodrow from #gfx irc.mozilla.org and Biotube from #radeon
irc.freenode.net told me.


start Firefox with 
layers.acceleration.force-enabled true
MOZ_GLX_IGNORE_BLACKLIST=1 firefox

(now dbg and backtrace)
ps afx | grep firefox
gdb -p 24318 (this is the firefox PID)
continue
backtrace

I get:
