Hi Ilya,

the statistics
https://crash.corp.google.com/browse?q=product.version%3D%2740.0.2191.0%27%20...
shows that they are coming from importer.
Please review.

LGTM, though I'm not sure what you're looking for at this point.  IIRC, the
in-process vs. external process importer code is used depending on which OS the
user is running.  Do you think that the empty usernames/passwords might come
from different sources on different OSes?

It would be interesting to know which browser we are importing from.
