Please provide some logging output for this check...

DCHECK(bubble) << "This will happen if ...";

Anything that will help someone troubleshoot what is going on...such as the
input values that caused the check.

I generally try to avoid DCHECK strings unless they're super useful.  If you
work on Chrome, you know how to check down a DCHECK firing.  Also, the strings
end up in our Release binaries (long story).

I don't have anything particularly interesting to say about this, it should
never fail.
