[transcode] critical: invalid filename

Running cluster with 3 nodes (including Cluster Master) I get errors when I
try to transcode when using either of the remote nodes,

kenya - cluster master
egypt - transcode  only
morocco - transcode only

The problem is consistent, reproducible  and always fails after a few
seconds.

 The error is as following and shows the transcode node morocco failing, the
same will happen with egypt. Kenya works ok. All machines are running
archlinux.

thanks for a great program btw.
