orca crashes

[Bram Duvigneau <bram bramd nl>]

Hi all,

I just installed ubuntu gutsy on a test system. However, after a while, 
orca crashes. Sometimes it's after a few seconds, or a few minutes, the 
crashes seem to be totally random. It could be a crash of the 
gnomespeech espeak driver, because the last braille output is still on 
the display for a while and switches to screen not in text mode after 
some time.

Any ideas what's happening here?
