problem when running trace

if a trace with more than 10 user, I get this error

Traceback (most recent call last):
File "socialccnsim.py", line 409, in
executor.run()
File "socialccnsim.py", line 182, in run
self.sched.run()
File "/usr/lib/python2.7/sched.py", line 117, in run
action(*argument)
File "socialccnsim.py", line 253, in consume_from_server
path = self.topology_nodes.get_path(social_issuer, row[1])
File "/home/moh/socialccnsim1/topology_manager.py", line 103, in get_path
return self.paths.calculate_path(self.topology_nodes[social_src], self.topology_nodes[social_dst])
KeyError: 18

Did anybody encounter a problem when running the example trace?

python -O socialccnsim.py 2 lce facebook abilene lru exampletrace/verysmall
