I noticed that I actually get the crash on Windows 2000 also quite often. 
Ethereal closes down without any error message at all, so the first times I thought that I had closed the main Ethereal by mistake.

I tried to use Visual C++ debugger and could see that the crash occurs on address 0x6dd12559.
There are some strings "WM_TRANSIENT_FOR" respectivelly "window !=0. gtk_window_set_transient_for" quite close
to that address.

The back trace information looked like this (when I had put a breakpoint some instruction before 0x6dd12559):

LIBGTK-0! 6dd12550()         I found the following string almost at that address:  "WM_TRANSIENT_FOR"
