No, because there is no bad filename/line number as the bad data is
coming in the form of a reply from the IMAP server.

The bad data is either a bad email or a bad reply from the IMAP server
that we cannot cope with. Therefore it would be good to know *what* that
IMAP reply is.

6.3.3 outputs more information, giving us the full traceback (ie in
which line the call failed). However that won't help you here, as we
know that it fails in that one "long()" call. It's just triggered from a
specific reply from the IMAP server. And as we have changed the code
From 6.3.2 to 6.3.3, I think it would be worthwhile checking it out.

It's as easy as downloading and untaring
https://github.com/nicolas33/offlineimap/tarball/v6.3.3

going into the directory and issueing "python offlineimap.py" in
there. No installation required.
