When it crashed, I was on a skype call while saving a file in gedit.

Why does the server not automatically restart?

I seem to trigger this bug occasionally when using copy/paste via right click menu. Happens in XChat, Pidgin and Firefox. I don't think it's specific to those applications though.

We are other important bugs in quantal and didn't get the time to fix them. In addition, we already live with that issue on precise. I think we should focus on the other bugs first and get back to this one later.

Can later be now, now? On a multiuser system I run, it's extremely frustrating to have Vino constantly dying, not to mention unsettling for my users to have a big, scary dialog pop up with “something something error something” on it.

David King from GNOME was fast and keen on the upstream report. He has already created a patch and asking for testing.
