When i try to import SingleScopeLens, i saw:
```
File "/home/nvbn/work/everpad/everpad/specific/unity/lens.py", line 3, in <module>
    from singlet.lens import SingleScopeLens, ListViewCategory
  File "/usr/lib/python2.7/dist-packages/singlet/lens/__init__.py", line 1, in <module>
    from singlet.lens.base import (
  File "/usr/lib/python2.7/dist-packages/singlet/lens/base.py", line 140, in <module>
    class SingleScopeLens(Lens):
  File "/usr/lib/python2.7/dist-packages/singlet/lens/base.py", line 57, in __new__

I echo this problem with the lens

[Alexey Kulik (doctor-rover)]

everpad-lens fails to start, producing the same output as in the bug description.

[Giacomo (poderi1980)]

I have the same output trying to run everpad-lens

Anyone found solution - workaround?

[SlavikZ (slavikz)]

Ubuntu 13.10 Unity 7 API has a lot of changes compared to Unity 5 API. For example, there is no Lens at all in the new API, but only Scopes.

For those who unable to use everpad-lens with ubuntu 13.10+ - you may try to use my unity-scope-everpad ( https://github.com/SlavikZ/unity-scope-everpad ) as a everpad-lens replacement.
