Import into Gmail hangs on a message that is too large

[lkowalczyk]

I stumbled upon this while importing messages from Fastmail (which allows attachments larger than 25M) into Gmail.

The log at the insane logging level is below. The normal and debug logging levels do not show the Gmail's error message, ie. "Message too large".

At this point the processing stops. I lost my patience after 20 minutes of waiting.
