O.k. I've found the problem.

This works with tar 1.13.25

tar cvjf test.tbz2 <files> --exclude=<file>

In 1.15.1 it mucks up parsing of --exclude=<file> and somehow later
tries to stat "--exclude=<file>" as being the complete filename. But
actually when it reports the "Cannot stat: No such file or directory"
message the filename is correct.

Moving --exclude=<file> to this...

tar --exclude=<file> -cvjf test.tbz2 <files>

makes it work.

Hope that helps,
