Well, the criteria are very  good as a general rule,
but in the case where a new/changed package reveals a *bug* in
R-devel (only), the package of course should still be released
to CRAN.
So the only remaining problem for you ;-)
is to convince the CRAN maintainers that indeed this is a bug in
R-devel, or probably in  zlib 1.2.4 (R 2.11.x uses zlib 1.2.3).

Within R-core, Brian Ripley has been the zlib "principal
investigator", and I'd wait a bit for his comment on this issue.
