Oops, Sage crashed. We do our best to make it stable, but...



A crash report was automatically generated with the following information:

  - A verbatim copy of the crash traceback.

  - A copy of your input history during this session.

  - Data on your current Sage configuration.



It was left in the file named:

	'/Users/wdj/.sage/ipython-5.0.0/Sage_crash_report.txt'

If you can email this file to the developers, the information in it will help

them in understanding and correcting the problem.



You can mail it to: sage-support at sage-support@googlegroups.com

with the subject 'Sage Crash Report'.



If you want to do it now, the following command will work (under Unix):

mail -s 'Sage Crash Report' sage-support@googlegroups.com < /Users/wdj/.sage/ipython-5.0.0/Sage_crash_report.txt



In your email, please also include information about:

- The operating system under which the crash happened: Linux, macOS, Windows,

  other, and which exact version (for example: Ubuntu 16.04.3, macOS 10.13.2,

  Windows 10 Pro), and whether it is 32-bit or 64-bit;

- How Sage was installed: using pip or conda, from GitHub, as part of

  a Docker container, or other, providing more detail if possible;

- How to reproduce the crash: what exact sequence of instructions can one

  input to get the same crash? Ideally, find a minimal yet complete sequence

  of instructions that yields the crash.



To ensure accurate tracking of this issue, please file a report about it at:
