it's clear that the current working directory is being added to the filename 
when the ./ form is used. That base url is obtained in the code at line 104 in 
url.c.

Can you copy the attached version of url.c to the pyRXP.../rxp/ folder (over the 
existing version). I have put some debugs into the code that's being used to get 
the base url.

I have done the same on my x_64 vm when I run this command I see this

ie everything appears normal when the ./xxx is converted into the file:// format 
and the script is working fine.
