CCing phil, meeks, eike. Are these console warning messges not a problem?
Comment 4 Michael Meeks 2015-07-03 15:07:22 UTC
Random accessibility related warning, almost certainly of no real interest =)

vcl/unx/gtk/a11y/atkutil.cxx-            case accessibility::AccessibleEventId::INVALIDATE_ALL_CHILDREN:
vcl/unx/gtk/a11y/atkutil.cxx:            g_warning( "Invalidate all children called\n" );
vcl/unx/gtk/a11y/atkutil.cxx-            break;

I guess we are missing a mapping to the native platform atk /toolkit for this event:

void DocumentFocusListener::notifyEvent( const accessibility::AccessibleEventObject& aEvent )
    throw( uno::RuntimeException, std::exception )

has no code; same warning on OS/X ... discuss =)

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.

* 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.

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.

On Writer, when going to insert->chart I have a different message printed:
** (soffice:27509): WARNING **: Exception in getAccessibleName()
It is printed until I leave the insert chart and can edit the document again.
