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 [1] "Package: lattice" "Version: 0.17-26" [3] "Date: 2009/10/05" "Priority: recommended" [5] "Title: Lattice Graphics" "Author: Deepayan Sarkar <[email protected]>" [7] "Maintainer: Deepayan Sarkar <[email protected]>" "Description: Implementation of Trellis Graphics.

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.
