I think it is a GTK+ problem. You can this crash e.g. when using
"wrong" drivers for your video card.
Unfortunately, I suspect that he's running Ethereal on a remote machine
using Windows Terminal Server (he mentioned WTS, presumably because
Ethereal is running on a remote WTS machine, not on his desktop
machine), in which case it's not displaying on a video card - the
driver is sending WTS protocol requests over the wire, not painting
pixels - in which case he might not have a choice of drivers.
I don't know why GTK+ has problems with those video drivers, although I
think WTS might only (at last in some versions) do only 8-bit color, in
which case GTK+ 1.2[.x] can't handle it in any case - it's supposed to
print an error, but it might be that, in some cases, it crashes
because, for example, some video card property is zero and it divides
by that value without checking it first.
I think I saw something indicating that the Win32 GTK+ 2.x doesn't have
the 8-bit-color limitation; it might also avoid the divide-by-zero
problem. Once we get the GTK+ 2.x performance to a reasonable level,
we might want to use it, rather than 1.3[.x], for Win32.
