Numerical result out of range in rdb 2.2.6?

[Derek Atkins]

Hi,

I've recently been attempting to backup my phone using rdiff backup.  Last
backup was successful 3 months ago (yeah, yeah, I know -- I should backup
more often).

I use mtpfs-simple to mount the phone as a file system on my Fedora-38
system and use rdiff-backup (rdiff-backup-2.2.6-3.fc38.x86_64) to sync it
to my laptop.  However, lately RDB has been barfing during the backup. 
The exact file where it errors out changes from attempt to attempt, but
the error always appears to be the same:

WARNING: Exception '[Errno 34] Numerical result out of range:

OSError: [Errno 34] Numerical result out of range: b'/path/to/file'


The command-line is:

rdiff-backup --exclude-globbing-filelist /path/of/my-excludes
/path/to/source-dir /path/of/backup-dir


Any ideas?

Version 2.2.6 is the latest version available on F38.
