Problem with Dovecot and BlackBerry

Hi all,

i've got a strange behaviour with a BlackBerry Classic Phone (BBOS  
10.3.2.2876) in combination with Dovecot 2.2.13 while trying to fetch  
mails.

Before burying myself into debugging sessions, i try to get an  
understanding if the following is a Client- or a Server-specific error  
in the behaviour:

CIGA8 UID FETCH 10009:10035 (UID FLAGS) (CHANGEDSINCE NOMODSEQ)
CIGA8 BAD Error in IMAP command UID FETCH: Invalid CHANGEDSINCE modseq.

Following the full conversation.

That's a broken client.

https://tools.ietf.org/html/rfc7162#section-3.1.4.1

"CHANGEDSINCE <mod-sequence>:  The CHANGEDSINCE FETCH modifier allows
   the client to further subset the list of messages described by the
   sequence set.  The information described by message data items is
   only returned for messages that have a mod-sequence bigger than
   <mod-sequence>."

Is that the dovecot.log file?

Here is what  I get:

# dovecot --version
2.2.28 (bed8434)

bbos 10.3.3.2205


Sanitized log file below. I'd appreciate the moderator removing my post
if I let something slip.

It would seem like a bug in your Blackberry email client, it should not
do this.

CIGA8 UID FETCH 10009:10035 (UID FLAGS) (CHANGEDSINCE NOMODSEQ)

The CHANGEDSINCE expects some numeric value, not NOMODSEQ.
