It seems I have exactly the same issue: installing the infusion on USB, running it will just stop it again in a few sec. When I run it in SSH it tells me:
File "/usb/usr/bin/sslstrip", line 27, in <module>
from twisted.web import http
File "/usb/usr/lib/python2.7/site-packages/twisted/web/http.py", line 37, in <module>
from twisted.protocols import policies, basic
