[rdiff-backup-users] exception when backing up files with uid or gid < 0

[Luciano Rocha]

Hello,

I have a problem where an application generates files with very large
uids/gids (4294967295 or -2). chown then dies with a traceback:

Traceback (most recent call last):
  File "/usr/bin/rdiff-backup", line 23, in ?
    rdiff_backup.Main.Main(sys.argv[1:])
  File "/usr/lib64/python2.4/site-packages/rdiff_backup/Main.py", line 285, in

    elif action == "backup": Backup(rps[0], rps[1])
  File "/usr/lib64/python2.4/site-packages/rdiff_backup/Main.py", line 305, in

  File "/usr/lib64/python2.4/site-packages/rdiff_backup/backup.py", line 51, in

  File "/usr/lib64/python2.4/site-packages/rdiff_backup/rpath.py", line 790, in 
chown
    else: os.chown(self.path, uid, gid)

This with latest stable version (1.0.5), x86_64:
# rdiff-backup --version
rdiff-backup 1.0.5
# uname -a
Linux app1.dc.aeiou.pt 2.6.9-48.ELxenU #1 SMP Sun Mar 4 19:50:03 EST 2007 
x86_64 x86_64 x86_64 GNU/Linux

Any fixes available?

Regards,
Luciano Rocha
