mismatched keys & citations about bibtex HOT 2 CLOSED

by renaming aplpack/CITATION to aplpack/xCITATION I prevent this issue.
So perhaps CRAN doesn't check for valid CITATION files in packages.
I've asked the maintainer of aplpack to fix or delete the problematic CITATION file.
However, the source .tar.gz for aplpack does not include a CITATION file, so I don't even know if the package owner or something in the process of generating windows binaries generated that problematic CITATION file.

This clearly isn't fundamentally a problem with bibtex, as the same package bombs citation(). However, because it can have huge but hidden consequences (mismatched key vs package for all packages after alphabetically aplpack), it there's an easy way to trap this error in bibtex::write.bib(), that could save other users hard to detect problems.
