David,
Thanks for looking at this.
My umask is ok, and i have several database files and they are not at
the default location. To reproduce the problem try this.
mkdir dtdir
darktable --library dtdir/lib.db --cachedir dtdir/cache --configdir
dtdir
I took a look at the change history and see the following changes. One
of which changed the permissions on the empty backup file from S_IRUSR
to S_IWUSR.
The unreadable file can not be backed up.
Greg

Maybe check your umask? I noticed that your backups are somewhere
different than mine, and also named differently (lib vs library).
