Crash when running dts-gen -m redux-actions

[joecoolish]

I just tried to generate a .d.ts file for redux-actions and I got the following exception:

Unexpected crash! Please log a bug with the commandline you specified.
C:\Users\ME\AppData\Roaming\npm\node_modules\dts-gen\bin\lib\run.js:107
        throw e;
              ^

Is there anything I can do to fix this issue?
