+Subject: [PATCH] avoid errors for application startup if no baloo index was
+ ever created
+
+use case:
+
+ * a KDE application started e.g. in an non-KDE Plasma environment
+ * a KDE application started with baloo indexing disabled
+
+you normally will get:
+
+kf.kio.slaves.tags: tag fetch failed: "Failed to open the database"
+kf.kio.slaves.tags: "tags:/" list() invalid url
+
+Now this is not issued if no index database exist.

+Subject: [PATCH] [BasicIndexingJob] Strip trailing slash from folders
+
+If BasicIndexingJob is called with a path with a trailing slash, the
+search for the last slash (separating name from parent path) goes wrong.
+
+This was wrong already earlier, but with commit 47ebc15844f6b8a8
+("[Document] Add parent document ID and populate it") this caused
+document and parent id to be the same.
