I've been using strata(sampling) and found that if the dataframe to be

order the run will fail on a given stratum. Ordering the dataframe
prior to using strata() eliminates this problem.
Thanks,

If you are reporting a bug, then as per the R FAQ and the Posting Guide, you are asked to report bugs on contributed packages to the package maintainer, not to the R Bug Repository. If you are simply reporting curious behavior for the benefit of others, then please post it to R-help and do not report it as a bug. I would still contact the package maintainer, who may wish to add clarifications to the package/function documentation. Marc Schwartz
