Installed the newest version of NB with the python plugin.
Use external python 2.6.2

When starting the debugger it connects to the socketb but fails with 

>>>hits = int(hits) 
>>>ValueError: invalid literal for int() with base 10

Added a print command in the jpydeamon.py file to have the value of hits and it seems to be an empty string

The full output:
>>>[LOG]PythonDebugger : overall Starting
[LOG]PythonDebugger.taskStarted : I am Starting a new Debugging Session ...
[LOG]This window is an interactive debugging context aware Python Shell 
[LOG]where you can enter python console commands while debugging 
>>>[stdout:]('SAMSAM', '', None, 'SAMSAM')Exception in thread MainThread:
