Comment 37 for bug 206547

This patch is only a partial solution to the problem but it's a start. In its current form, the first message received for a new conversation that is not the first (in other words, the first message of a conversation to open a new tab instead of a new window) does not set the urgent hint or update the window title. Any subsequent messages behave normally. This is because the new-message signal needs to be connected to earlier, but I need to go to bed and can't figure out how to accomplish this right now. Hopefully someone else will have time, or I will later. Anyway it can't hurt to post here in hopes that someone else will look at it.

Upstream says that this feature should not be merged for lucid anyway as it needs more consideration on how to be done right. I'm not sure I agree with them, but they should be represented none the less.
