Selecting QRE Tool Crashes Gambit

[DuncanFoley]

I set up a simple strategic game. I can compute NE and dominated strategies, but selecting QRE crashes the program.
Running El Capitan (Mac OS 10.11.3)

Gambit 14.1.0 installed on Mac OS 10.11.3 (El Capitan)
Python 3.5.1
Game file won't attach below, but you can download it at
https://www.dropbox.com/s/rnw0jspubxx9hao/CournotExample?dl=0
In the Tools menu I can select Dominance or Equilibrium, but when I click Qre the program quits

without warning.

Attaching the file for posterity. As a tip, if an attachment doesn't work, something like a gist is much better for long-term storage. (Once the link above breaks, the report will be useless.)

Dear Ted,

Thanks for straightening out the file.

When I open this file in Gambit and choose Qre the program quits without warning.

I second this issue on Ubuntu 15.4. One workaround I found is to model the equivalent game in extensive form and then use the QRE solver.

As of today, this does not happen on MacOS. It might be happening on Windows (although I tried the Windows executable running under Wine so there could be a confound there).

There is no obvious reason why this should work fine for agent QRE but not for strategy QRE.
