the problem is not related to the compression code. If I first repack to
xz without Files-Excluded, and then repack from that with
Files-Excluded, I get the same error:

$ mk-origtargz --repack --compress xz ../src.tar.xz 
Successfully repacked ../src.tar.xz as ../liboptimization-java_0.1.orig.tar.xz, deleting 22 files from it.
$ tar taf ../liboptimization-java_0.1.orig.tar.xz

The problem is a bug in tar:

$ uncompress src.tar.Z
$ md5sum src.tar

mk-origtargz could possibly print a warning. Added that (giving not the
very nicest output, but it should not occur too often).

Greetings,
