No speech in gdm3 with Orca

[Sebastian Humenda <shumenda@gmx.de>]

Hello,

since a while I don't have speech while I'm logging in with gdm3. I've
activated Orca in gdm3 and copied my local preferences to the
Debian-gdm user (/var/lib/gdm3) and changed the ownership of the files. 
Everything worked, until some days ago orca started up and remained silent. 
The braille display works as expected. When I open the orca preferences
and then press OK, the settings get loaded again and the speech is
back.
What is wrong there?
System: Debian (mostly) Squeeze (everything from xserver and related
to GUI is already squeeze).

Thanks
Sebastian
