It may be the other way around. I had lot of problems talking to other users
(who were using MSN) when I used WebMessenger

I was working well with the previous version of Kopete.

It worked for me.
But webmessenger is slow, and a large delay is required before the message appears.
It's anyway something we can't fix.

I confirm that it doesn't work. It is not the delay. It was working with the
previous version and IT WORKS with Gaim. So the problem doesn't come from
webmessenger.

I think we should reopen the bug.

Please provide me debug information. (are the message sent over the network?)
Or explain me how i can reproduce it.

Because i've tried it and it works.

Well if you say it works it's really strange.
The messages are sent on the network. I've asked someone who uses MSN to send a message to the contact that don't work, and he can't. But with gaim it works...

Could it be because of a proxy or something like that ?

I will ask my contact if i can put hi address here, so you could try yourself.

i tried again, and it works perfectly.
If you don't show me the proof that Kopete do something bad, i'll can't fix it.

It could be because a bug in the webmessenger. or a problem with your browser, or i don't know.

Here is my contact.
audeduigou@hotmail.fr

When i send her a messagen she gets disconnected. But it works with GAIM or MSN.
It's quite strange... You can test it by yourself, i've aksed her permission to give you the contact.

Hope it will help

CVS commit by ogoffart: 

Even if no font are sent, we should sent an empty font name. this is better than nothing. Or WebMessenger will fail
