No Pictures with Kodi 17.3

Hello,

I try to view some pictures on my Kodi 17.3 via Twonky server UPnp/DLNA. I sideloaded Kodi on the Fire TV Box, for videos all works fine. The problem with pictures is, that I got the folders and subfolders but not one picture to see. Sometimes the navigation into the subfolders breaks also down without an error message. I try to reinstall Kodi and Twonky but with no effect

The URL for te Debug Log: https://paste.ubuntu.com/24964284/ if this is useful in any ways

Kind Regards
