+Subject: [PATCH] libtracker-data: Do not load vtabs if vtab data is missing
+
+We have one case of direct use of tracker_db_manager_new() in
+"tracker3 export" CLI command to (ab)use it to open databases from
+2.x. This doesn't pass a TrackerDataManager nor requires creating
+the usual 3.x virtual tables.
+
+Avoid this virtual table creation in that case, and subsequent
+crashes when trying to access the NULL data manager from those.
