14.04 logon screen: Orca starts up and immediately shuts down

[Nick Wood]

Hi all,

I'm running Ubuntu 14.04 (32-bit) and have Orca set to start automatically
at the logon screen, but I'm getting some weird behaviour:

Basically what happens is this:

1. I get the sound of the drums.
2. Orca says: "Screen reader on.  Login screen frame. Screen reader off."
3. I then have to start up Orca again using the Alt+Super+S combination and
after that it seems OK.

I don't see this behaviour on my Fedora 22 box - just the Ubuntu one.

Anyone got any ideas why Orca is shutting down?  The fact that it says
"Screen reader off" makes me think it's a controlled shutdown rather than a
crash.

Thanks,

Nick
