I was  answering a  post/thread on Opera's  forums. Had  done preview,
made a  correction to the  post, then did  <alt w d> to  duplicate the
tab. Exit stage left. crash log to follow.

Core was generated by `/usr/local/lib/opera/9.50-20080229.1/opera -style motif
-notrayicon -geometry 9'.
Program terminated with signal 11, Segmentation fault.
