On a table with table-layout:fixed, when you have 1 row with a fixed height and another row with a div with height 100%, the table's height is more than 100%.

Reproducible: Always

Steps to Reproduce:
1. Open the attachment
2 [review]. Resize your window, make it small enough so that the content doesn't fit.
3. Pay attention to the overflow of the lower cell.
Actual Results:  
The lower cell grows, thereby making the table higher than 100%.

Expected Results:  
The lower cell (and its inner div) gets a height of 100% - 200px and the scrollbar is on the inner div, not the page.

A recent Webkit/Safari build will display the expected behaviour.

The question is what the min height of a table cell should be when no height is specified.

This isn't covered by the CSS spec, and the webkit behavior causes issues in some cases...  There are, I believe, existing bugs about this particular case.
