Bug#862008: crashes, segmentation fault

[Mika Hanhijärvi <miksuh@gmail.com>]

When I read the discussion in Gnome bug page I see that some people have 
regular Orca crashes which happen often e.g when they close some 
application. Luckily I have not noticed problem like that. Orca crashes 
do not happen often or regularly on my computer, just sometimes. I also 
have not had Orca crashes when I have closed applications. I think those 
crashes have happened mostly when I have switched between apps running 
on different Gnome virtual desktops. I run just one application on each 
virtual desktop.
