Three different Debian unstable users reported / confirmed the issue. A
simple test would be what has piled up in the bug reports, eg as demonstrated
by ChenLiang things break once we wrap gzfile() around:
readLines(gzfile(system.file("DESCRIPTION", package="lattice")))
returns nothing with the 1:1.2.3.4.dfsg-2 version whereas I on testing -- and
the unstable users who downgraded -- get the whole record:
~> echo 'readLines(gzfile(system.file("DESCRIPTION", package="lattice")))' | R
--slave

You should be able to run this on the shell.
Let me know how I can help. I should be near email for the next 10 hours when
we're off to another little neighbourhood Xmas party.
