hmm..strange
did you have installed the last version?

if you wrote:
it won t work : it needs a space after 'python'

well the suddently closings are due to this f*** python-location module which breaks everything..
if it closes..launch it again.. and launch the gps-localisation again..if it closes one more time..hmm
you'll have to delete the *.pyc files..it will be slower but i don't understand the deal.

become root and type:
rm /opt/rtap/*.pyo

Try and tell me
