Hi Bertrand,
I've been looking at that warning, and it seems that the problem comes  
from the base_app.py source.

This file is from the demo system itself, so it's something the we  
need to fix, but it's not related to your particular demo. Thus, if  
the demo works you just can ignore the warning.

If the base_app.py, the signature for function params(...) is the following:
     def params(self, newrun=False, msg=None)

BUT, in input_select, a "key" parameter is passed: return  
self.params(msg=msg, key=self.key) (this causes the warning)

and also in input_upload: return self.params(msg=msg, key=self.key)

Nicolas Limare is about to fix a problem we have with that key  
parameter, so it's worth looking at that warning and fixing it when  
the new code is uploaded.

Best,
Miguel
