[rdiff-backup-users] exclude questions

[remi . delmas . 3000]

Hi everybody!

I'm having a hard time using the exclude/include options. (I'm running
rdiff-backup 1.1.7 with the fsync patch under cygwin)

I want to backup a directory which can sometimes contain *.obj, core, or *.mp3
files that should not be backed up.

So I tried rdiff-backup --exclude **/*.mp3 --exclude **/*.obj --exclude **/core
/home/myself /backup

This works fine when there are actually mp3 and obj files in the source
directory, but rdiff-backup exits in error when there are no such files:

Fatal Error: Fatal Error: The file specification
    '**/*.mp3'
cannot match any files in the base directory
    '/home/myself'
Traceback (most recent call last):
  File "/usr/bin/rdiff-backup", line 23, in ?

in _get
    raise ConnectionReadError("Truncated header string (problem "
rdiff_backup.connection.ConnectionReadError: Truncated header string (problem
probably originated remotely)
receiving file list ... done

Is there a way to have rdiff-backup get over this type of situations without
exiting in error?

Thanks for any help you can bring me,
