+Subject: [PATCH] Check return value of createNodeFromUDSEntry()
+
+createNodeFromUDSEntry() can return a nullptr, which it does when
+passed any URL from the baloosearch protocol.

+Subject: [PATCH] UDS_URL is not meant for links, Use UDS_TARGET_URL instead
+
+The KIO documentation for UDS_URL says:
+`use UDS_TARGET_URL if you want "links" to unrelated urls.`
+So the use of UDS_URL here was probably wrong.
+Switching to UDS_TARGET_URL fixes mounting of some slaves such as baloosearch,
+which set UDS_URL to the URL of the entry itself for some reason.
