Thanks for finding that, Nick.

Going back to what Olivier said:

I think (please correct me if I'm wrong) he was more referring to my 
suggestion to not include any session client support in libxfce4ui at 
all than to my proposal to ditch SM support in core xfce apps.  So maybe 
Olivier wasn't totally opposed to removing SM support from xfdesktop.

Thinking back on it, I guess I wouldn't be opposed to SM support in 
libxfce4ui, unless we decide that the X11R5 SM support in libexo is good 
enough for most apps.

My previous point here still stands -- the thought of hardcoding our 
apps in xfce4-session sounds like a bad idea.  Even offering a 
configurable list of apps to always keep running sounds like a bad idea. 
  If we're going to do that, we might as well just implement the respawn 
bits of the SM protocol.

This was actually the entire motivation for my initial suggestion, so, 
yeah, I'm well aware of this.

I'd love to say we can fix all crashers so it's never an issue that apps 
fall out of the session, but I'm trying to be realistic here.
