+Subject: [PATCH] imjournal bugfix: module did not work at all
+
+The open function was broken by commit 92ac801 (v8.30.0),
+resulting in no data being ever read from the journal.
+
+patch bases on the idea of Radovan Sroka given here:
+https://github.com/rsyslog/rsyslog/issues/1895#issuecomment-339017357
+but follows the current imjournal-paradigm of having the journal
+handle inside a global variable.
+
+see also https://github.com/rsyslog/rsyslog/issues/1895
+closes https://github.com/rsyslog/rsyslog/issues/1897
