We're failing one of the marked asserts in [1], but I can't tell which.

Probably one of the first two. It's also probably a NaN somewhere.

Richard, what type of headset were you using during this call?

Comment 3

[Julien Cristau [:jcristau]]

This is low volume, not something we'd fix in a dot release.

(In reply to Paul Adenot (:padenot) from comment #2)

> Richard, what type of headset were you using during this call?

USB, either a Plantronics 628USB or a C520-M.
