Dear Maintainer,


using iceweasel, going to http://lcamtuf.coredump.cx/afl/demo/ then pressing
the first "click here" link which points to:
http://lcamtuf.coredump.cx/afl/demo/jpeg/full/
these are some example inputs from the afl fuzzer.
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:
