I found some files that the automatic unrar cannot seem to handle.
The naming is a bit odd, but 7z handles them with no problem.
The files were named
file.part2.rar
file.part2.r00
...
I suspect newsbin gets confused as file.part2.rar could also be part of a <= 9 part rar set with another naming convention.
I'll mail an exampe search to ts.
