My terminal output is pasted below, bug report is attached.
I tried emailing sage-supp...@googlegroups.com per the terminal output -
didn't work (bounced). Sagemath homepage 'Report a bug' brought me here.
OS is Debian testing amd64. Sage installed from Debian testing repos. Crash
occurs immediately on executing sage.
Thanks
Chris

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:
'/home/c/.ipython/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-supp...@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-supp...@googlegroups.com <
/home/c/.ipython/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:
