Trying to resize left column in user profile results in weirdness

Trying to resize left column in user profile by dragging the separator (see screenshot 1) results in redirecting me to an interesting and informative page (see screeshot 2).

Experienced on AtlasEye 2.7.0-M2 Build:20110705045157, using Chrome on Ubuntu 11.04. (<- the Environment field does come in handy at times!)
