Have you looked at rpy.assign(...) command? e.g.
rpy.assign("dir1", "/home/foouser/foo/")

Very odd.
Out of interest, why are you doing string concatenation in R using
paste, when you can do it directly in python with plus? Something
like this perhaps, using python's os module to mess about with the
paths...
import os
rpy.assign("dat.file", os.path.join(rpy.r("dir1"), "prices.txt"))
[The above would be simpler if dir1 was available as a python variable]

It certainly looks like there is a bug here somewhere...
