Smartshine fails to save images

[Hans Joachim Desserud]

Steps to reproduce:
1. Run smartshine (preferably from a terminal)
2. Click the button to "add photos"
3. Select a random image
4. Click the "Save all button"

Expected behaviour:
The image is stored on disk. (There's a couple of options to manipulate the image before storing it, but that is not neccessary to trigger the error)

Actual behaviour:
The application seems to load, but never finishes. The following error message is printed in the terminal:
Exception in thread Thread-2:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 810, in __bootstrap_inner
    self.run()
  File "/usr/share/smartshine/smartshine/smartshine.py", line 481, in run
    Gui.save_to()
  File "/usr/share/smartshine/smartshine/smartshine.py", line 427, in save_to
    self.rm_if_exist(item[0], saveto) #remove existed _new files
  File "/usr/share/smartshine/smartshine/smartshine.py", line 238, in rm_if_exist
    if os.path.isfile(where + "/" + self.fileaa):
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

Due to bug 1702367, I am unable to test this on newer releases.
