This appears to be a gnome-shell crash with superficially similar
symptoms. Please report it as a separate gnome-shell bug instead of
replying to an unrelated gdm3 bug: if you have successfully logged in,
then you are no longer interacting with gdm-simple-greeter.

The gnome-shell maintainer will probably ask for information from your
~/.xsession-errors, so you can save some time by attaching that.

>From the name of the crashing thread, this is probably related to this
gnome-shell change:

gnome-shell (3.4.2-7+deb7u1) stable; urgency=low
...
    + Add a watchdog thread to suicide the process after 10 seconds if
      the GC locks up.

Thanks,
