Brasero: can't choose a directory.

[William Mattison]

I'm using Fedora-23, last patched last Thursday, 6/23.

Last Friday, I was trying to back up some directory trees to DVD.  I 
launched Brasero, and chose "New Data Project".  The result should have 
been a list of the directories and files at the home or root level.  The 
file list area was blank.  When I try "Project" -> "Open", a populated 
file browser shows up.  I can navigate the file system successfully, but 
I can't find a way to select a directory for copying to the DVD.

This all worked in March in F-22, when I backed up before upgrading to 
F-23.  What am I doing wrong?  Or what have I not done that I need to do?

Thank-you in advance for your help.
Bill.
