If you manually click to save more than one session, the next time you login, it will fail to load *any* session, and instead, fire up the default session. This is a big pain.
Don't know about this bug. Did anyone look at this?
The same happens to me whenever I try to save my session while exiting. I run debian unstable, xfce4 4.0.5-1 + xfce4-session 0.1.3+20031213-2
Indeed, I've seen this behaviour several times, though your xfce4-session is way out-dated. I'm currently rewriting xfce4-session, and from what I can say now, I haven't seen this behaviour since then. Anyways, I'll leave this bugreport open until its sure that the bug is fixed.
This seems to be fixed since the first 4.x version of xfce4-session.
