Far out: a signal from the new exoplanet?

Gliese 581g is a big deal, the first known exoplanet in its star's "habitable zone." Do we already know something about life on it? Australian astronomer Ragbir Bhathal claims that, two years ago, he detected a sharp pulse of laserlike light from the same general area of the sky.
COMMENT: Not buying this as evidence of ET? Me neither. Bhathal never saw his pulse again, and no one else saw it even once. By the way, there's no official name for this planet, just the designation. I vote for "Krypton" - a habitable world with several times Earth's gravity.
