Extrange problem in Chrome (not in firefox) about mipmap 0

I have isolated an strange problem that only appears in Chrome (not in firefox), no matter which OS, and machine. It renders the mipmap 0 totally black.

You can see it here: http://tamats.com/apps/test/webglchromebug/ just drag the mouse in the canvas to move the camera (if the camera doesnt move, reload the page).

I cant call it a bug because I guess Im the only one experiencing this problem but I guess there is something about WebGL that Im missing here.

Im using lightgl.js (a tiny wrapper for webgl calls) and the code is kind of straight forward regarding to upload the texture to webgl.

Does anybody else has experienced this problem?
