* common/t-sexputil.c (test_ecc_uncompress): Ignore unknwon curve errors. -- For unknown reasons some versions of Fedora or RHEL provide a patched version of Libgcrypt with Brainpool support removed. We better ignore this error because it is a regression in 2.2.28 although that older versions could not used Brainpool keys. GnuPG-bug-id: 5502 Signed-off-by: Werner Koch <wk@gnupg.org>
