Same thing happens to me, but it does not only involve MSN but any account. I use normal jabber (jabber.org) and facebook too, happens for both of them.

The conversation window simply closes. For me Empathy didn't hang.
When sending message from Gnome 3's instant messaging box, the message is sent but it does not appear in the box.

Maybe I will try to run Empathy in debug mode later and provide some more info...

I can confirm this bug. I don't think that telepathy-butterfly crashes (the account is still connected and you continue to receive messages) but the conversation window closes every time a message is sent.

The behavior is the same as Dénes, but only with MSN. Facebook Chat, Google Talk or plain XMPP works.

don't confirm it. debug it and start providing proper debug traces.

https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces#One_package_settings_only

Will try to send you debug information soon.

Now I got sure I was wrong: It only involves MSN.

Another question: Is this surely the empathy package? As I found out that chatting somehow became a core gnome functionality where you don't have to run any main windows for empathy but you can still chat. Is the code responsible for the chat window still in the empathy package?

I only updated empathy and got this issue, I would assume something is up with empathy, as the latest 3.0.x release worked just find and I never updated butterfly/papyon. Unless one of the GNOME 3.2 packages are conflicting with it. I get no 'new' error output in terminal

Also, it seems to happen in both the chat window and the gnome-shell integration.

Same here; pressing enter after typing msn chat windows makes the chat window close.

should i ask again for a better trace? Adding "same here" messages doesn't help anyone.

Sorry bout that, I'll try to post a trace when I get home tonight.

I would like to note that I've been digging a bit, and out of process of elimination, it might also be caused by folks or telepathy-mission-control, if it helps at all.

try to downgrade telepathy-glib to 0.15.5

I just tried it on my laptop during my lunch, it seemed to have fixed it. I had to compile it from source because it's not in the ARM. I compiled it without using the supplied patch, if that matters at all.
Do you still need a trace?

Also the message integration stopped work, I assume that's what the patch is for?

what patch? that is only for 0.15.6 and you shouldn't apply it for 0.15.5

Oh okay, either way it worked excluding the integration is broken, do you still need a trace?

i don't understand what happens after you downgrade to 0.15.5.

it doesn't crash anymore?

Sorry I didn't mean to be vague. When I downgrade, it seemed to work great but with one problem.

The problem is that the integration window does not show any new incoming or outgoing messages, only the previous conversation history that's loaded when the window is opened. I can send messages using the integration, and the conversation window works just fine. Downgrading fixes it but provides another issue.

I haven't tried the downgrade of telepathy-glib, but I want to clear what looks like a misconception about this bug.

Nothing crashes, I've just compared the list of processes before and after sending a message and it's the same (well the differences are unrelated to this problem). The conversation window closes, but it isn't the result of a crash from Empathy or whatever… Everything continues to run, the account is still connected (I can even chat using the Shell integration, but without seeing my own messages).

However, there are some weird stuffs happening sometimes after the bug, like some accounts going offline (not only the MSN account) and right now, I sent a message to myself but a friend received it (I was trying to chat with him earlier but could not because of the bug).

you guys should report this upstream and help them finding the issue. i'm confused.

Hi, please find a backtrace from /usr/lib/empathy-chat (the binaries which crashes) attached, with
*empathy 3.2.0-1
*telepathy-glib 0.15.6-2

Note that the libs are not build with flag -g.

Should I provide something else ? No bug filled upstream yet, but some bugs which could be the same at fedora tracker.
https://bugzilla.redhat.com/buglist.cgi?query_format=specific&order=relevance+desc&bug_status=__open__&product=Fedora&content=empathy

recompile glib2,gtk3 and telepathy-glib then report to gnome bugzilla, empathy

Hi, I can confirm mission-control bug too. Using Msn protocol crashes mission-control and closes chat window.
Under bugs and mission-control section in empathy I found this: "_mcd_channel_set_status: assertion `channel->priv->status != MCD_CHANNEL_STATUS_FAILED' failed"

report to bugzilla.freedesktop.org

telepathy-glib 0.15.7 should fix the butterfly bug

Ok, things work fine (built without the patch in the current package, works with gnome to)

telepathy-glib 0.15.7 fixed it for me too.
