Comment(by talex5):

 (sorry, maybe 0sugar is the wrong component but I couldn't find a better
 one)

 zeroinstall/injector/download.py uses sys.executable to run a new copy of
 Python. This doesn't work under rainbow, because sys.executable is wrong
 for some reason.

 e.g.

 Use rainbow-easy to get a new shell. Run:

 {{{
 0launch --gui http://rox.sourceforge.net/2005/interfaces/Edit
 }}}

 This gives the error "[Errno 13] Permission denied".
