Still getting Signal 11 error msg

[fergus]

After some recent large updates including XFree* and tetex* and texmf* I am
still getting a "Signal 11" error msg after a request to xdvi a .dvi file.
This is after starting XWin -multiwindow and when running rxvt -display.
Anybody else getting this or similar, or recognise the symptom? Thank you.
