Thanks for the informations you provided. I have been able to narrow the
problem to version 2.6.1-6 (ie 2.6.1-5 works). Given the short changelog
of this version, I guess the problem is located in the following changes:
   * Add any/cvs-posix-glob.diff, fixing improper of treatment of \
     in glob(). closes: #445210

I need some more tests to confirm that the problem comes from this change.
