Iwamoto-san and I saw this symptom frequently at least since
XFree86-4.1.0 (or perhaps even 4.0.x).

The following patch (for 4.1.0) from iwamoto-san fixes this symptom:
	http://mail-index.netbsd.org/tech-x11/2002/01/08/0000.html
But this patch isn't incorporated into our tree.
(This patch simply disables a new feature of XFree86-4.x.)

There is another patch for this problem as follows:
	http://mail-index.netbsd.org/tech-x11/2002/01/09/0000.html
And this one seems to be already incorporated into XFree86-4.2.0 and
our xsrc tree. But unfortunetely it seems this one doesn't really fix
the symptom.

As you see in the backtrace, this symptom often happens while scaling
a large (i.e. 16bit) font. So, only chinese, korean, taiwanese and
japanese users may notice this problem usually...
