PR: https://github.com/apache/arrow/pull/45
> Segmentation fault on len(Array) for empty arrays
> -------------------------------------------------
>
> Key: ARROW-80
> URL: https://issues.apache.org/jira/browse/ARROW-80
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Reporter: Uwe L. Korn
> Assignee: Uwe L. Korn
>
> When creating an Array with no underlying storage (do we want to allow
> this?), i.e. before init is called, len will run into a segmentation fault.
> This is especially annoying if you only want to try it out in an ipython
> shell and the line `pyarrow.array.Array()` directly crashes as IPython tries
> to print the repr.
