[Bug 1056300] Re: orca quits after closing the greeter with "install now" option

[Luke Yelavich]

I've found the problem. If I'm reading Ubiquity's GTK frontend code
correctly, the main loop is shut down when the installer switches pages.
Commit 5debed5ae247c1dd440cb71d0a6d328df74b0844 introduces some extra
code to make sure accessibility is properly shut down when the mainloop
quits. The problem here is that accessibility is initialized when
gtk_init is called, so in ubiquity's case, switching installer pages
causes the main loop to quit, which shuts down accessibility, but when
the main loop is started again, there is no accessibility enabled for
ubiquity any more.

** Package changed: ubiquity (Ubuntu Quantal) => gtk+3.0 (Ubuntu
Quantal)

** Changed in: gtk+3.0 (Ubuntu Quantal)
       Status: Confirmed => Triaged

** Summary changed:

- orca quits after closing the greeter with "install now" option
+ If a GTK application quits the main loop and restarts it again, accessibility is lost.

Bug description:
  On the quantal beta 2 image - 20120925, I'm trying to do the
  screenreader test.  So far I've been able to reproduce this with both
  i386 and amd64+mac.  After starting orca, things seem to work ok
  through the welcome screen in ubiquity, but then it quits reading.
  Starting with the screen titled "Install" with the text at the top
  "Preparing to install Ubuntu", it doesn't read the screen any longer.
  Nor does it seem to tell me when I press keys like enter to move on.
  Other apps are still read to me after this by orca though.
