Thanks for your bug report. I can confirm this on Linux and Windows XP. The "extent" property is correct for ordinary text objects, but not for a uicontrol like your example. The first two elements of the "extent" vector should also be zero, as mentioned here:

get( h, 'extents' ) returns too small width/height.

hf  = figure;
h   = uicontrol( 'parent', hf, 'style', 'push', 'string', 'foo', 'fontsize', 32 );
pos = get( h, 'position' );
ex  = get( h, 'extent' );
pos(3:4) = ex(3:4);
set( h, 'position', pos )

It seems multiplying ex with a factor of 2 works.
