Getting really worried, I hit the "Help" link in gmail. Turns out that I can either go through a stupid automated troubleshooting procedure that didn't help at all or I can post my problem to a discussion forum that is sometimes visited by the gmail admins but mostly they assume that your problem will be solved by a user. I did post about my problem there but since this morning I am unable to find that forum anymore. Err..
I don't know on which end the problem exists but if you are reading this mail and you work at either o-hand or google, kindly investigate this issue.
UPDATE: I figured out the issue. Eric created this cool looking "@gstreamer.net" alias for me once and I had been advertising that all around. Turns out that I even used this alias/redirection to subscribe to (o-hand) mailing lists. I subscribed to clutter ml using '@gmail.com' address and I instantly got the messages from the list. I'll write to Eric in hope of getting the lost mails but I must stop using this alias/redirection no matter how cool it is.
