Public bug reported:
Dear Orca package maintainers and developers,
If in Orca preferences dialog I enabled contracted braille feature into
preferences dialog with Braille page the enabled contracted braille check box
and click OK button, Orca screen reader after settings reload is freeze.
This issue is true if Liblouis version greater with Liblouis 3.3.0 version,
Ubuntu 18.04 containing now with Liblouis 3.5.0 release.
Testcase:
1. Launch orca with orca --replace command if contracted braille is not enabled
(this is the default preference).
2. Press Orca modifier+Space keystroke. If you using desktop layout, the Orca
modifier key is insert or numpad insert keystroke. If you using laptop layout,
the orca modifier key is caps lock.
3. Goto braille page, and click enable contracted braille check box.
Expected result after Orca settings is reloaded:
Screen reader still usable.
Actual result:
Screen reader entire unusable.
I tested this issue with Ubuntu 18.04 Mate edition beta release I386
architecture version in a KVM virtual machine.
