Commit 39bd063 seems to break the listing of camera recordings

[minsonj2016]

I have been using Motion for over a year now . I have a locally built docker image which has worked fine .
Recently I decided to update so I re-created the docker image using the source code from "master" .
It built with no issue and I thought it was OK until I tried to list the camera "RECORDINGS" . When I click the camera name under "RECORDINGS" it fails silently . The click does nothing .
If I build a new image that stops at commit 2e325a7 it works again .
If I build a new image stopping at the next commit , 39bd063 , it stops working .

Setting the log level to 7 doesnt seem to show anything of interest .

Could this be a config problim ?

Here is the log file
motion.log

I forgot to add that if the recording directory is empty I see the header line of the recordings listing . Its only after a file is written into the directory that this issue starts .
