21.2-b20 crash on Solaris 2.7

I was in VM reading a folder, and pressed "q" because I was done. XEmacs crashed. If it helps, I had the gutter tabs on. Here's the Lisp backtrace: resize-subwindow(#<image-instance (widget) on #<x-device on ":0.0" 0x2202> (#<face default "defau lt face">)Buffers 648x21 on #<x-frame > 0x198ca00 0x27be6> 648 nil) # bind (inst locale frame-or-buffer) update-tab-in-gutter(#<buffer "cmucl-commit">) delete-window(#<window on "cmucl-commit Summary" 0x278eb>) # bind (delete-me done all-frames start w obj-2 obj-1 action) vm-window-loop(delete #<buffer "cmucl-commit Summary">) # bind (buffer) vm-maybe-delete-windows-or-frames-on(#<buffer "cmucl-commit Summary">) # bind (vm-mutable-frames) # (unwind-protect ...) # bind (vm-sbe-buffer buffer) vm-undisplay-buffer(#<buffer "cmucl-commit Summary">) # bind (wf w) # (unwind-protect ...) # bind (vm-sbe-buffer do-not-raise configs commands display buffer) vm-display(#<buffer "cmucl-commit Summary"> nil nil nil) # bind (summary-buffer pres-buffer mail-buffer virtual no-change) vm-quit(nil) # bind (no-change) (lambda (&optional no-change) "Quit visiting the current folder, saving changes.
