--- Comment #5 from Peter Vágner <pvagner at pvagner.tk> ---
Hello,
I am on Arch linux, Gnome 3.32, Libreoffice 6.2.1 and I am getting a different
behaviour which I think is even worse than originally described here.

Steps:
* Make sure orca is running
* Start libre office
* Create an empty spread sheet document
* Press F10 to bring up the menu bar
* Navigate to Insert -> Chart...
* When the dialog box comes up don't change a thing and press the Finish
button.

Results:
Libre office and the whole accessibility stack will lock up allowing no further
interaction unless I restart orca by running
orca --replace
from the terminal.
After restarting orca Libreoffice is still running however as soon as I alt+tab
back to its window I can experience the whole lockup again.
So without more hints I am unable to collect more details as while a11y is
locked I can't use my machine at all.

I think this is more serious than intended originally.

Part of the terminal output captured while accessibility is locked like this.
