If you've got a new profile, you need to reset the junk folder in the profile; that's not implemented as a property on the IMAP server, AFAIK.

I should have checked the names: those prefs, as you can see, are set for 'default' rather than for 'server2' (or whatever the serverN value is for your IMAP account). As far as TB is concerned, there is no junk folder set for your account; the icon confirms only that that particular folder is not set as a junk folder.

After you explicitly set the folder (and restarted) the icon did not change?
The spamActionTarget prefs didn't appear for that account? Then it may well be that there's a different, IMAP-specific problem here; I can't say whether the patched version will fix it or not.

To my knowledge, no.
