[Evolution] Search folder dies with this condition

[Jeremy Nell <jeremynell gmail com>]

I'm using IMAP with my Gmail account.  If I create a search folder
(within specific folders such as Inbox and Sent), then it all works
fine. 

If I want the condition to include messages sent AND received from, say,
John Doe, then I create two conditions: one as "Sender contains" and one
as "Recipients contains".  This works fine.

However, if I use the single condition "Sender or recipients" for the
same person (which, as I understand, is the above two conditions merged
into one). then everything falls apart; the folders become blank and Evo
goes mad in the status bar, "retrieving" this and that, but seemingly
not getting anywhere.

Am I doing something wrong?
