consider (on linux):
it returns /home/vtorri//Pictures/foo, that is an additional / before Pictures. It's the case on linux or Windows.
It is the case for : desktop, documents, downloads, music, pictures, templates, videos, data and tmp
note that usr.public, while in eina_vpath.h comments, is not recognized (hence, abort)
segfault too with "(:app.bin:)/foo" etc...
