I'm having HTTrack hang at various seemingly random times. 
It doesn't seem to be with any particular site or after any
particular amount of time (5 hours, several days, it
varies).  If I do ^C and then Cancel, it starts running
again as if nothing had happened.  The log file shows little
of interest:

20:42:06        Debug:  result for wizard link test: 0
20:42:06        Debug:  Testing link type
counter.nope.dk/link.php3?id=15414
20:42:06        Debug:  (Keep-Alive): live socket closed
#13542 (counter.nope.dk)
08:46:25        Debug:  Changing link extension
counter.nope.dk/link.php3?id=15414 to .html
08:46:25        Info:   engine: save-name: local name:
counter.nope.dk/link.html -> counter.nope.dk/link20df.html

Next time it happens, I'll give it a segfault and see if I
can get a core out of it.
