Filesystem storage conversion

[RaymondCM]

Sometimes the pickled files on disk cannot be unpickled (wrong data format).

  File "/home/raymond/catkin_ws/src/topic_store/src/topic_store/filesystem.py", line 63, in __iter__
    tree = pickle.load(fh, **load_kwargs)
  File "/usr/lib/python2.7/pickle.py", line 1384, in load
    return Unpickler(file).load()
  File "/usr/lib/python2.7/pickle.py", line 864, in load
    dispatch[key](self)
  File "/usr/lib/python2.7/pickle.py", line 1212, in load_setitems
    dict[stack[i]] = stack[i + 1]
IndexError: list index out of range

It seems to work for conversions between .topic_store and database but converting to .bag returns the following error:

I haven't seen that error in my tests Niko, could you send me the file you're trying to convert?
