1.7.3 IE bug on profile widgets

There seems to be a display bug on version 1.7.3, "/pg/profile/<USERNAME>" in Internet Explorer 7 and 8.

where there is a large vertical space between #widget_table td "#widget_table td",  and div id = "widgets_left" and div id = "widgets_middle".

I did my best to hack this one out, but had 0 success after several hours, has anybody worked this one out?
