Hi,

i developed my ryu-app using the snort-devel branch of 
ryu. Now i tried to port it to the current version of ryu.
But when i use the --observe-links option of the 
app-manager, i got this Error which i cannnot fix:

hub: uncaught exception: Traceback (most recent call 
last):
   File "/home/openflow/ryu/ryu/lib/hub.py", line 48, in
