As far as I tested, you were right: tar 1.13.25 is "stable" and the
"bug" I reported is gone

Thanks and sorry for the false-bug-report,
Niels

please use tar-1.13.25, not 1.13.  It is normally available from
ftp://alpha.gnu.org/gnu/tar/ but it seems that there are currntly some
temporary problems.

Either use an FTP search to find tar-1.13.25.tar.gz , or get the orig
tar.gz from eg. Debian distribution or src.rpm, or (the highest hack
value!): get the current development tree from the tar CVS, see
http://savannah.gnu.org/cvs/?group=tar
and http://savannah.gnu.org/projects/tar

If you decide to use the CVS version, your chances that you find another
bug are better that with good old 1.13.25.  ;-)

One of the tricks is to know which version to use.  Though 1.13.25 from
alpha.gnu.org is called ``development,'' most GNU/Linux distributions
use
it and I don't know about any problems.  I'd say this is a bug which has
already been fixed during the development of 1.13.25.  (Incremental
backups are relatively new feature, and 1.13 is 4 years old.)

I hope I'm right when I say that the tar maintainer hesitates to release
a new stable versions, as he knows about some bugs which are present
in 1.13.25 but have not been present in 1.13.

And, BTW, when replying to me, please keep the cc: to bug-tar, in order
to get the discussion archived, and to deliver it to the devlopers too.

HTH,
