irule editor - linux

I installed the linux vim version. When I ran ":Co ip_address", it hang and eventually displayed this error:

 

 

maximum recursion depth exceeded

 

Error detected while processing function Connect:

 

line 10:

 

Traceback (most recent call last):

 

File "", line 6, in

 

File "", line 13, in get_objects

 

UnboundLocalError: local variable 'ltm' referenced before assignment

 

Press ENTER or type command to continue

 

 

There is no problem with login credentials.

 

 

Any idea what the cause might be?
