EOFError: Compressed file ended before the end-of-stream marker was reached

[Dieter Heußner]

Hello,

I deploy rdiff-backup for a few major main directories (source).

One of these main folders on backup media causes problems according to
rdiff-backup -v9 --check-destination-dir  /mnt/usbdisk/FOLDER

The most recent error message is:
EOFError: Compressed file ended before the end-of-stream marker was reached

The problems are NOT with rdiff-backup, but with *rdiff-backup-delete*, that is 
I can 
successfully backup files from source directories to backup media, but I am 
*not able to 
delete files* on backup media with rdiff-backup-delete.

Checking *.gz files on backup media:
Running
find /mnt/usbdisk/FOLDER/rdiff-backup-data -name '*.gz' | xargs gzip -vt
creates a list of about 50,000 entries.
Half of these entries carry "OK" in them,
the other half complain about "No such file or directory".

Questions:
1. How to get rid of this problem?
2. Can one DELETE ALL *.gz files in /mnt/usbdisk/FOLDER/rdiff-backup-data so 
that rdiff-
backup creates it from scratch?

Any help appreciated!

Thank you very much in advance!

Best regards
Dieter
