Fails to calculate free space for long mount points

Binary package hint: easycrypt

easycrypt Version: 0.2.2.5-0ubuntu1
installed onto a standard gutsy system with latest truecrypt installed
My home directory is nfs mounted.

When trying to create a crypt in my home directory it gave the following output:
username@hostname[32116]% easycrypt
failed to load localised text, defaulting to English (en)
Easy Crypt 0.2.2.5 (2008/01/23 22:34:45)

found truecrypt
df -k /home/user/ | tail -1 | awk {'print $4'}
size left 99%
Traceback (most recent call last):
  File "./EasyCrypt.py", line 1504, in doFirstCreateEvent
    self.getCryptPasswordThenAction("create")
  File "./EasyCrypt.py", line 872, in getCryptPasswordThenAction
    spaceleft = self.howMuchSpaceInKb()
  File "./EasyCrypt.py", line 408, in howMuchSpaceInKb
    return int(checkAmountLeft)
ValueError: invalid literal for int() with base 10: '99%'

This is caused by df using two lines to display long mounted filesystem names.

e.g.
% df -k ~
Filesystem 1K-blocks Used Available Use% Mounted on
fileserver:/home/username
                      21165056 20751360 413696 99% /home/username

A solution is to patch /usr/share/easycrypt/EasyCrypt.py to use df's -P (posix compatibility) flag.

e.g.
% df -Pk ~
Filesystem 1024-blocks Used Available Capacity Mounted on
fileserver:/home/username 21165056 20751360 413696 99% /home/username
