Cannot handle mount points with spaces in them

[MarcelWaldvogel]

bedup fails when any btrfs filesystem is mounted on a path with a space in it. This happens when a file system with a label with a space in it is automounted. It also happens when a filter without spaces (e.g., /dev/sdxx) is given to select this file system.

Sample output:

# bedup dedup
Traceback (most recent call last):
  File "/usr/local/bin/bedup", line 11, in <module>
    load_entry_point('bedup==0.10.1', 'console_scripts', 'bedup')()

    sys.exit(main(sys.argv))

    obj.__dict__[self.__name__] = result = self.fget(obj)
  File "/usr/local/lib/python3.5/dist-packages/bedup/filesystem.py", line 191, in root_info
    fd = os.open(self.minfos[0].mpoint, os.O_DIRECTORY)
FileNotFoundError: [Errno 2] No such file or directory: '/media/marcel/Backup\\040Marcel\\040Waldvogel'

Could it be that the mount point path is escaped too many times?
