+From 69968dec867053e38de0b91d76ac41d5a5735e36 Mon Sep 17 00:00:00 2001
+From: Vendula Poncova <vponcova@redhat.com>
+Date: Thu, 2 Aug 2018 15:31:56 +0800
+Subject: [PATCH 2/2] Support transformation between D-Bus errors and
+ exceptions.
+
+Exceptions can be registered with decorators, raised in a remote
+method and recreated after return from the remote call.
+
+Upstream-Status: Cherry-pick [https://src.fedoraproject.org/cgit/rpms/python-pydbus.git/]
