Comment 1 for bug 508873

Just looked into it, and it's due ot permissions:

Traceback (most recent call last):
  File "/usr/share/kabikaboo/src/kabikaboo.py", line 1231, in save_document_callback
    self.file.save(self.document)
  File "/usr/share/kabikaboo/src/file.py", line 110, in save
    if self.save_to_file_pickle(self.working_file, document):
  File "/usr/share/kabikaboo/src/file.py", line 293, in save_to_file_pickle
    output = open(filename, 'w')
IOError: [Errno 13] Permission denied: '/home/aidave/Documents/Scripts/Creation Myths/Kabikaboo/CreationMyths-80.kaboo'

So it should be giving the user a warning.
