Those of you who do not care about the light leak issue, please don't bash those who do care for one reason or another. May be you will never run into the issue with the type of photography you do but there are legitimate reasons that this will affect certain types of photography.
The problem is, when the scene is dark enough for the "problem" to manifest itself, it's also too dark for the meter to work reliably. If you think that the meter is giving you the "right" exposure in those dim conditions and the backlight / LCD is throwing off the meter, you're just fooling yourself. The fact of the matter is that, if you're using the camera's meter below EV 1, it's all just an approximation...and, if you're using it below EV -1 (where the "problem" first begins to show up), the meter is little more than a rough guesstimate.
Sure, use it to get a test exposure in the ballpark when you're doing long exposure or insane ISO work. But please don't kid yourself that the meter is right. The proper way to get the right exposure is either by intelligent reading of the preview and histogram, or by bracketing. Or, in the case of insane ISO work, by realizing that you're not going to get National Geographic
-quality results in the first place, so don't even pretend to worry about it.
And, oh-by-the-way, I've yet to even hear of a photographic meter (dedicated, built-in, or otherwise) that's designed to produce trustworthy results below EV -1, so it's not like this is a problem with the camera.
