When using MOZILLA_NEWTYPE=tab, starting seamonkey causes this error:
/usr/lib/seamonkey/mozilla-xremote-client: Error: Failed to send command: 509 internal error
Browser doesn't understand command
The first instance starts normally, this only happens with the following ones. It isn't too tragic, thus it should hold you off from marking seamonkey stable. I guess not a lot of people use this variable.
I can reproduce with seamonkey-1.0.6, this might have something to do with https://bugzilla.mozilla.org/show_bug.cgi?id=349549
This seems to be an upstream issue, mozilla-launcher ends up calling:
/usr/lib/seamonkey/mozilla-xremote-client -a seamonkey 'openURL(,new-tab)'
It seems to explode because the URI is not entirely valid, if you feed it a valid URI it will work flawlessly.

This is indeed strange, I'll report it upstream tomorrow most likely.
Certainly is an upstream bug, feel free to prod them:
