log from running origin up untill the login screen that displays the message

Since the latest update (a few days ago), EA Origin displays the message
"Online login is currently unavailable"

It won't allow me to log in

I'm running the latest wine, version 1.7.15 on archlinux x86_64.
I've tried the following:
-start over in a fresh prefix with WINEARCH=win32
-install Qt5 as described in the appdb entry
-use winetricks to install vcrun2008 and vcrun2010
-recompiling wine, in case an update broke it
-running it in a windows vm in case the server is actually down (it isn't)

I don't recognise anything out of the ordinary in the log, other than the
"CLSCTX_REMOTE_SERVER not supported" message. I'm not sure it wasn't there
before, but it also displays in Steam and that works fine.
