Two information to add to my problem :
First, I didn't notice that, but the problem appears only with enumerated
types.
Secondly, I have debugged the script with pdb and it shows that it crashes
in the file client.py when putting the type (INTEGER) into a list called
self.__dict__ (line 60 of this file) :
{'iid': '17', 'tag': 'rbQoSProfileType', 'type': 'INTEGER', 'val': '0'}
Maybe these two information will help you finding the problem, because for
me, I don't know...
Thank you
