[Evolution] Bug#531838: evolution: unusably slow since upgrading to 2.26

[Phil Blundell]

Package: evolution
Version: 2.26.2-2
Severity: important

Since upgrading evolution from 2.22 to 2.26, mail operations in general
(and switching between folders in particular) have become many times
slower than they used to be.

Specifically, I have two commonly-used IMAP folders which each contain a
fairly large number of emails: about 200,000 in one and about 100,000 in
the other.  With the old evolution, I could switch between these folders
almost instantly (so long as the message headers were already cached
locally, of course).  In the new version, changing between these two
folders takes about a minute.  This is sufficiently bad as to make
evolution almost unusable since the upgrade.
