"A suitable transcoding job already exists" error - Linux

I am trying to play transcoded video to my PS3, but I am getting an error. One thing I noticed in the log is the message "A suitable transcoding job already exists, re-use it for client 'IPAddress=/192.168.1.147, Profile=Playstation 3'", which is not true, I never played this movie before. FFMpeg is never even invoked, because serviio thinks the file is already transcoded? The relevant log lines are

One would think that Serviio would actually check if the "suitable transcoding job" file actually exists before determining to use it. On top of that, the /tmp folder is emptied on reboot, so keeping some sort of database of videos which are already transcoded is kind of ridiculous. /tmp/Serviio is an empty directory right now.

[zip]

So FFmpeg fails. The renderer makes 2 quik requests, the first starts FFmpeg, the second checks if the transcode for the file had started (in this case yes and doesn't star FFmpeg again). In the meantime you get the FFmpeg failure from the original request.

If you are on Linux make sure you have up-to-date FFmpeg.

I definitely checked, FFmpeg is up to date. And I am not even seeing a call to ffmpeg, which is usually shown in debug mode. Is there some sort of database where serviio keeps track of which movies already have been transcoded?

[zip]

No, they are transcoded on-the-fly and then removed.
