An issue with this signature was fixed in bug 1845350, but it looks like it has started showing up on Android. I don't know if the volume is sufficient to be a problem, but I figured I'd file a new bug.

:padenot do you any insight why this might have come back? maybe bug 1839193?

The crash rate was significant for a few days, but is low now.
