CORE leaving an article from within gnuclient

Hi! Current CVS version of xemacs. I exited xemacs on the fast lane by leaving an article in Gnus. I was working within an xterm running gnuclient -nw. C-trace as follows: #0 0x185653d0 in kill () from /usr/lib/libc.so.3 #1 0x80c7323 in fatal_error_signal (sig=6) at emacs.c:535 #2 0xbfbfdfdc in ??
