Cannot Download Mail from Self to Mailing List Using GMail Extension

[Gil]

I sent mail to a mailing list of which I am a subscriber.

It shows up in my GMail inbox.

The Webmail extension does not download it.  It leaves it in the GMail
inbox.

I am using WebMail 1.3.11 and GMail 0.6.7b1.

I can send log files if desired.
