Description of problem: From IRC: <@ajax> mbarnes: i have evo set to do ~30 minute checks for new messages, plus automatic message filtering, and the folder view shows only unread messages. when it checks for new messages, and some new ones get filtered into the folder i'm currently in, the message i'm currently on gets marked as "read", and therefore disappears. Even when new messages don't filter into the current mailbox, the view panes still flash. These might be separate bugs, or might not. Version-Release number of selected component (if applicable): evolution-2.10.0-2.fc7
I think the flashing is a separate bug. I've seen it reported elsewhere and can readily reproduce it myself. It seems to only happen with longish messages. I think GtkHTML is using a refresh timer while it renders the HTML, but it's erasing itself and then redrawing the whole thing with each refresh. Hence the flashing. For REALLY long messages you'll notice the flashing gets slower as more of the message is rendered, I guess because it takes longer to draw. Anyway, for this bug I'll focus on the message list behavior you described.

Un-duping. 247332 is about the flashy refresh, this is for the message list thing.
Oh, whoops, sorry. I don't even remember closing this one. CC'ing Milan.
Do you really think this is a bug? The updating folder thing. Evo just every ~30 minutes call update on each folder and then refreshes view. Which is probably correct, right? I remember I did a patch, included definitely in 2.21.91, which ensures there always selected any message, when the actual "disappear" (either deleted, filtered out or anything else). It _tries_ to find the "nearest" message from the old one. Is this enough for this issue?
I think Adam's issue is the fact that a selected message in a folder gets marked as read when new messages get moved into that folder via filters. If your view is only showing unread messages, the message may disappear on you while you're still reading it.

Upstream bug for this is http://bugzilla.gnome.org/show_bug.cgi?id=467892 Can we track it there? The problem is much complicated than it can seem to be.
Hmm, OK, I attached a proposed patch to upstream bug, we will see what they say. I'm closing this as 'upstream'.
A patch for this has been committed upstream. Is it possible to port, or at least make sure it is updated for F9?
Sure, it's committed to stable branch too, which means next update will include it. I heard they plan next release on this Friday, so after that we will update our package too.
