shutil in python error

[Alec Wright]

Binary package hint: python2.5

When you use shutil.copyfileobj in python in ubuntu gutsy, it will fail and return an error.

Here is the script I used:
#!/usr/bin/python
import shutil
shutil.copyfileobj('/dev/zero','test','1024')

It returns this error:
alec@alecomp:~/Programming/xbyte$ ./xbyte
Traceback (most recent call last):
  File "./xbyte", line 3, in <module>
    shutil.copyfileobj('/dev/zero','test','1024')
  File "/usr/lib/python2.5/shutil.py", line 21, in copyfileobj
    buf = fsrc.read(length)
AttributeError: 'str' object has no attribute 'read'
