Test case

User-Agent:       Mozilla/5.0 (Windows NT 5.1; rv:2.0b8pre) Gecko/20101211

See test case.
Right after the call to InitializeComponent of the Form, we do:

Rectangle rec = this.tabControl1.GetTabRect(0);

With .NET, this returns:

With Mono, this returns:

However, if calling the GetTabRect method later on, Mono returns something more
sensible (although a bit different from .NET). So I suspect GetTabRect returns
an empty Rectangle until the TabControl has been drawn for the first time, or
something like that.

Reproducible: Always
