+Subject: [PATCH] abrt-journal: call sd_journal_get_fd() right after
+ sd_journal_open()
+
+See: rhbz#2128662
+
+Under certain circumstances, abrt-dump-journal can be running,
+but not receiving any event notifications from journal.
+
+The culprit of the issue seems to be the delayed call
+to sd_journal_get_fd(), as discussed in various
+issues and pull-requests in other projects.
+See for example [1], [2], or [3].
