Hi Brice,

thanks for the report... evil cut/paste and as always -- there could be
more unittesting ;)

I have fixed it, and will push shortly in GIT master.   next release
candidate is probably approaching so updated packages will come soon
into NeuroDebian.  Meanwhile, if you really want to try it -- just run
that script in '-O' mode, then all those debug printout calls will not
be ran... e.g.

python -O myscript.py


python -O /usr/bin/ipython

if you want such ipython session ;)
