I manage to get a core dump with this url-list:

http://alpha.mkn.co.uk/help/flower/info
#http://anther.learning.cs.cmu.edu/priest.html
http://artaids.dcs.qmw.ac.uk:8001/entrance/entrance.html

There might be something strange that happens after we have visited 
"flower/info".  Some more checking seems to indicate that any URL checked 
after "flower/info" will give a segmentation fault.

The server itself seems quite normal to me:

$ telnet alpha.mkn.co.uk 80
