[Pkg-virtualbox-devel] Bug#793338: virtualbox: VBox crashes when run with a screen reader

[Jean-Philippe MENGU‘AL]

Package: virtualbox
Version: 4.3.18-dfsg-3+deb8u3
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

I use Orca, MATE, qt-at-spi.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

1. Run /usr/lib/virtualbox/VirtualBox
2. Go to Machines menu (alt-m)
3. With down arrow key, choose "Configuration" (or Settings)
4. Browse 1-2 tabs with down arrow keys
5. Press Escape

   * What was the outcome of this action?

I get a segfault.

   * What outcome did you expect instead?

Should back to the main Vbox window.

*** End of the template - remove these template lines ***

See attached log. I can install gdb/valgrind and, if you tell me commands,
help to see where's bug (tracking). I just need your instructions to use debug
tools. You also need to tell me what symbol debug you need.


Regards,
