[solved] Error splicing file: Illegal seek (rclone)

Im still having problems with rclone or owncloud; the call as I suggested:

/usr/bin/rclone mount Owncloud: --vfs-cache-mode writes /home/me/OnlineDrives/Owncloud

Seems that some apps like Skrooge accounting dont like this transport as I get lock-ups regularly. Direct file copy and download seem to be OK.
Any comments appreciated. Al.
