+Subject: [PATCH] OCI: correctly handle locally present icons
+
+If the download URL for an icon was already cached locally, the HTTP
+code returned FLATPAK_OCI_ERROR_NOT_CHANGED - this was treated as a real
+error, and after downloading missing icons, all present icons were
+deleted!
+
+See https://bugzilla.redhat.com/show_bug.cgi?id=1683375
