[Pkg-sogo-maintainers] Bug#920423: sogo: Exception thrown on "rich" email view after 4.0.5 upgrade (from 3.2.6)

[Matthew Hall]

Package: sogo
Version: 4.0.5-2
Severity: grave
Justification: renders package unusable

Dear Maintainer,

I’ve just upgraded (and due to reasons entirely my fault, I’ve realised I have no downgrade path… backup fail) from 3.2.6 (I believe it was) to 4.0.5.

It’s a Debian box, using the “official Debian sogo packages” - I’m now running on Debian Buster (due for release later this year).

Everything is working a charm - upgrading the database appears to have worked perfectly - all except the “/view” URL used by the AJAX UI for retrieving a “rich” email from a folder...
(So by extension, I simply cannot view emails in the SOGo webmail client.)

Works using “viewsource” (as in, the SOGo 'viewsource' button works - which makes sense because I can see the IMAP debug is working properly on the backend), and the headers download properly etc.  I’m seeing an exception thrown in the logs:


Jan 24 22:41:11 sogod [2864]: <0x0x560efac4c220[NGImap4Client]> TLS started successfully.
Jan 24 22:41:11 sogod [2864]: 10.0.90.34, 10.0.20.10, 10.0.20.11 "GET /SOGo/so/matthewhall/Mail/0/folderINBOX/64252/viewsource HTTP/1.1" 200 1584/0 0.549 4041 60% 0
(worked)

(failed)


(Note it’s a “GET” request and not a “POST” because I’m reproducing it manually, not via the AJAX UI in this example.)

I’ve tried with all the debugging enabled in sogo.conf and I don’t see anything unusual: IMAP works perfectly, then sogod throws the exception above.

Any ideas?  I’ve exhausted all my own - and I can’t see that it’s a known bug (I've also reached out to the SOGo user's mailing list on the off-chance).
I’ve by-hand confirmed the database structure looks correct for a 4.0.5, but I may have overlooked something.  I briefly tried it against a fresh database too, and that behaved the same (again, unless I was overlooking something silly).

I cannot rule out the possibility of user error on my behalf - but I'm 90% confident it's an issue in the 4.0.5-2 package.
(I've not been able to try other 4.0.x debian packages - but can do so if they are available.)

No other obvious issues like missing packages etc.

Very happy to provide any other information like database schemas etc if that would help.
