Dear Maintainer,
using iceweasel, going to http://lcamtuf.coredump.cx/afl/demo/ then pressing

instead of displaying, the screen went black and i was logged out. the gdm
login screen was shown.
~/.xsession-errors contains nothing particular.
however, /var/log messages contains these interesting lines:
