That did not help.

Establishing connection to imap.gmail.com:993                                   
Creating new IMAP folder '[Gmail]/Important' on server Remote

I have removed the folders in question locally (they seemed to be old
leftovers), but now it syncs weird things:

Syncing INBOX: IMAP -> Maildir                                                  
Adding flag a to 12 messages on INBOX 

Syncing idc: IMAP -> Maildir                                                    
Adding flag a to 74 messages on idc                                             
Deleting flag S from 186 messages on idc

The latter folder has not been touched in weeks, and what is flag a?

Downgrading to 6.3.4 and resyncing reverses these things:

Deleting flag a from 12 messages on INBOX
Deleting flag a from 74 messages on idc
Adding flag S to 186 messages on idc

Something seems to be seriously broken there.
