[Evolution] Sorting Emails by date

[Harvey Nimmo <harvey nimmo de>]

I set up my emails so that the newest email is always at the top of the
list, i.e. Sort by Date(descending). However, Evolution seems not to be
consistent in this respect. 

I suspect that Evolution displays one data/time in the message (list)
window but sorts by another date/time from the several date/time tags
from among the mails' metadata.

This leads to an (unhelpful) inconsistency in the email sorting is
displayed. For instance, I have a series of mails in my inbox supposedly
displayed by date (descending), but showing dates in the following
order:
Thu, 3 Oct 2013 17:10:26 +0000 (03/10/13 19:10:26)
Sat, 28 Sep 2013 19:41:31 +0000 (28/09/13 21:41:31)
Tue, 1 Oct 2013 15:21:51 +0000 (01/10/13 17:21:51)
Wed, 2 Oct 2013 15:57:00 +0000 (02/10/13 17:57:00)
Wed, 2 Oct 2013 17:07:41 +0000 (02/10/13 19:07:41)
Sat, 28 Sep 2013 20:39:55 +0000 (28/09/13 22:39:55)
Wed, 02 Oct 2013 07:41:33 +0200
Tue, 1 Oct 2013 23:12:43 +0200
Tue, 1 Oct 2013 23:12:43 +0200
Tue, 1 Oct 2013 21:10:00 +0000 (01/10/13 23:10:00)
Mon, 30 Sep 2013 07:03:21 +0000 (30/09/13 09:03:21)
Sun, 29 Sep 2013 15:43:41 +0000 (29/09/13 17:43:41)

I have seen this kind of behaviour in Evolution for years but never
complained about it! Has anyone else mentioned it before?

Cheers
