The input file (emailed to shaka-packager-issues@google.com) plays fine with ffmpeg and worked fine with shaka-packager v2.6.1-634af65-release.

I'm also getting a Segmentation fault on v3.0.0, v3.0.1, v3.0.2, and v3.0.3 when decrypting an mp4a.40.2, which has almost the exact same stats as you, but unlike you my file succeeds with dump_stream_info:

When decrypting:

I still have the file but I have no further information other than it works on v2.6.1. The above results were with v3.0.3.
