It seems that when set-face-attribute is called on the `default' face to
change some font-related property (the family in this case), it does a
`modify-frame-parameter' to change its `font' setting which in turn then calls
`face-set-after-frame-default' to refresh all the faces which in turns
tries to use the `default' setting which changes the `family' again, ...

Looks like a bug.  Does it also happen under Xwindow ?
Please reply to gnu.emacs.bug.

That bug is fixed already for 21.3.

No, it doesn't happen under X on Linux. This problem is only happening 
with Win2k.
