Why do e.g. ssh sessions hang when I try to log out?

I've noticed this a lot recently. I want to run an X app off another
machine, say thunderbird. So I do "ssh -X user at host" to log in and run
thunderbird from the command line. When I get done, I exit thunderbird
and get a command prompt back. Then when I hit ctrl-D or type "exit"
or whatever, the session hangs. When I hit ctrl-C it finally exits.

As a test, I just did this against my local F16 machine, and I tried
to log out after using thunderbird as a different user.

I see that I have these processes running as my user:

tcameron  5615  0.0  0.0  22356   764 ?        S    14:10   0:00
dbus-launch --autolaunch 812e3e28dfa6439dcc2013e
tcameron  5616  0.1  0.0  29932  1156 ?        Ssl  14:10   0:00
/bin/dbus-daemon --fork --print-pid 5 --print-ad
tcameron  5619  0.0  0.0 136548  2744 ?        S    14:10   0:00
/usr/libexec/gconfd-2

So it appears that dbus is not letting me log out. This is merely an
annoyance, so I'm not sure it's really a bug. Even if it is, I'm not
sure it's worth reporting as a bug.

Anyone else notice this?
