+Subject: [PATCH 1/2] PolkitUnixSession: Set error if we cannot find a session for the given pid
+
+Also, don't treat the integer returned by sd_pid_get_session() as a
+boolean because that's just confusing. Also, don't confuse memory
+supposed to be freed by g_free() and free(3) with each other. See
+
+ https://bugzilla.redhat.com/show_bug.cgi?id=787222
+
+for more details.
