In imap/mboxlist.c mboxlist_parse_entry() we except to get the  
uniqueid if we found a extended mboxlist entry.

Indeed the entry is extended on the mupdate servers mboxlist and on  
the backend server. But the mupdate server has no uniqueid.

I guess this is the problem here. state->mailbox fails in annotate.c  
before we test if uniqueid is set there:

Line 1680 in annotate.c...:

     assert(state->mailbox);

     if (state->mailbox->uniqueid)
         buf_appendcstr(&value, state->mailbox->uniqueid);

Btw: Is there a good reason not to store die ID in the mailboxes.db.

output of strings on the backend...:
# strings /var/lib/imap/mailboxes.db
twoskip file
6user.test%(A %(test lrswipkxtecdan) I 02tws5d0y4ecnp9rhgy66p5m P 00 V  
1502362835 F 1 M 1502374944)

output of strings on the mupdate server:
strings /var/lib/imap/mailboxes.db
twoskip file
user.test%(A %(test lrswipkxtecdan) P 00 S mailsg-hx T r M 1502449874)
