It is a very minor dent but horizontal mid tube is not a good spot. Creasing a tube does reduce the strength. A hard landing or hard bump is where that would likely be the first point of failure. Even if that section has lost 50% strength it would take a lot for the bike to fail. The rest of the frame is there and even 50% strength on that section is a lot ...

Just off the picture I'd say it's fine. Aluminum is more durable than many people think (you know they build airplanes out of the stuff?!) That said, I would carefully look at the areas where the tubes are welded together. Use a bright light and look for any small, hairline cracks in the paint. Most of the aluminum bikes I've seen fail usually snap at the ...
