Currently, the implementation of gUM expects
- The parameter to gUM to have both audio and video constraints to have non-falsy values.
- Both a video and audio source to be available.

The implementation crashes since UserMediaRequest::constraintsValidated expects defined parameters audioSource and videoSource.

This turned out to be a bug in unrelated code.
