dynamically changing a button's font

[beach ataman com]

I've been working on some gtk code which quite frequently needs to
change the style used by some of the controls on the screen.  When
dealing with a label, I've had much success with something like:

label.set_style(new_style);

(where new_style is set to use a different font than the label's
former style.)

However the same code doesn't seem to work at all when I use it with a
button.  I read the styles.txt and it seems to indicate to me that my
code should be working.  Any ideas?
