Never.  

Well, never directly.  I'm using gtkplot from the gtkextra package.  

To date, while I've described my problem on that mailing list, I've
never had enough data to make a useful bug report, or even to
definitively say that the error is in that code.  The crash only happens
when I'm plotting, but there are other widgets and manipulations that I
do when plotting.

I've tried to look into the gtkplot code, but it is, shall we say,
"sparsely" commented.

Is gdk_draw_points() the ONLY gdk call that could produce a PolyPoint
request?  If so, I can start looking through the 5 or 6 gtk_plot...()
calls that I make when refreshing, and try to find a gdk_draw_points()
that is shortly after an allocation or recreation.

[Brief research]
I would guess not, as gtkextra never uses gdk_draw_points, although it
does use gdk_draw_point.  For that matter, only in gtkcurve.c does GTK
call gdk_draw_points().  For the most part, both use gdk_draw_point()
instead.  I wonder if XFillPolygon() would cause a request code
PolyPoint?

One new data point, it does not seem to happen when using the Solaris
Xserver.  I have't done enough tests to establish "never" for a fact,
but it is "less" prone to the problem than when using the eXodus Xserver
on NT.  I wonder if my Xserver is non-conforming, or if the Solaris one
is just more robust/careful/prompt in allocating.
