Well, strace sure dumps out a lot of info, mostly 
incomprehesible to me.  Several runs all end with something 
like that below.  Only two lines stand out to me:  (1) the next 
to last line where strace stops scrolling.  The interrupted 
call may occur when I click on opera's continue button.

pid  5648] <... poll resumed> [{fd=9, events=POLLIN}], 1, 2000) 
= -1 EINTR (Interrupted system call)

and (2) the line which prints about a minute later as the 
system halts, containing "segmentation fault."  

write(2, "/usr/bin/opera: line 72:  5613 S"..., 
67/usr/bin/opera: line 72:  5613 Segmentation fault      $OPERA 
"$@" ) = 67

/usr/bin/opera is only 72 lines long and line 72 reads only

$OPERA "$@"

Could this segmentation fault be the cause of the problem or is 
it just the result of a failed attempt to log the failure?

In the copy below, I have marked the beginning of each line 
with an @ mark since I'm set up for 60 character lines.
