Fresh Conda install has only partially functioning Spyder

[statespace]

Description

What steps will reproduce the problem?

1. Install Conda on fresh Ubuntu (Mint 17.3 64-bit):
   bash Downloads/Anaconda3-2.5.0-Linux-x86_64.sh
   conda update --all
2. Run Spyder
3. Tools -> Preferences

Nothing else is installed / executed

What is the expected output? What do you see instead?
Preferences do not load, instead there is internal console error:

>>> /home/avalujevs/anaconda3/lib/python3.5/site-packages/nbformat/current.py:19: UserWarning: nbformat.current is deprecated.

- use nbformat for read/write/validate public API
- use nbformat.vX directly to composing notebooks of a particular version

Editor and console works (at least on simple examples) as intended. Just no access to preferences.
