Thanks for trying that out. The exact error we're getting is "xm002 NO [NONEXISTENT] Unknown Mailbox:
[Gmail]/All Mail (Failure)"
The gadget is hitting your All Mail folder and requesting details of the email you are on, so that it can pull out the names of attachments. And in response, it's getting back that the mail box "All Mail" doesn't exist..........
It's the same problems Contacts would have. It's using IMAP to find out the First and Last Name of the person who sent the email so that we can fill that in for you, and we're getting the same response.
Those are really the only two areas it uses IMAP, so that's why they are the only areas you are having problems with.
Good news (maybe). I was able to duplicate the error, however, I had to make some settings changes in order to do it.
I went to Settings > Labels in Gmail, and then beside All Mail, on the far right, there is a "Show in IMAP" checkbox. I checked that off, and voila, I now get same error you are getting.
Do you have that checkbox? Can you turn it on?
