Hi KiBi,

Unfortunately I couldn't reproduce this by torturing iceweasel with that
huge picture.  I'll keep the debugger attached for some time, but
enabling core dumps seems more viable in the long run.  Please let me
know if there's a canonical way to do that (other than hacking the init
script).
