Public bug reported:

Binary package hint: sbackup

The lock file generation in sbackupd.py is not atomic as it tries to
open the lockfile for read and if this fails it creates it by opening it
for write.

Something like:

try:
            fd = os.open(path, os.O_CREAT | os.O_EXCL | os.O_RDWR)
except OSError, e:
            if e.errno != errno.EEXIST:

should fix the issue.
