+Subject: [PATCH] a-dump-journal-core: First seek the journal tail and then set
+ filters
+
+See: rhbz#2128662
+
+a-dump-journal-core uses filters to jump between
+systemd-coredump entries in journal.
+
+However, we should first jump to the starting position
+(journal tail) and only then set filters.
+I suspect that setting the filters early, before we are
+at the starting position, can lead to the strange
+behavior that we are seeing in Fedora.
+
+This patch makes the problem go away on my freshly-installed
+Fedora 37 VM.
