evolution didn't close after clicking on X but went into suspension mode with all menu inactive. killall - could not find processes but ps - displays them running.

Clicked on evolution X to close it. Evolution didn't close and everything went inactive. Cannot select email or folder (inbox, sent, etc) and only thihg that is active are window control buttons. Still X does not close the window.
tried in terminal 'ps aux | grep evolution' and got a result in:

tried to 'killall evolution' but this do not find process as well. Only logging out kills evolution.
It has happened to me several times. Also on one occassion when evolution was open - on bottom of it's window service messages shown up: 4 of them with "Unknown operation in progress" and 1 with "checking for new messages" (or something like that). Weird.

Just tried to killall gcalctool and found out that it kills it only by 'killall gcalctool' and not by a process id.
I suppose this is another bug but don't know how to report it.
