Re: Serious accessibility issue in Gnome 2.15.

Hi all,

A few interesting findings:
The below tests were conducted on An Edgy system with latest updates as of Tuesday August eight:

1. I downgraded gnome terminal, by building and installing gnome-terminal-2.14.2.tar.gz, as well as vte-0.12.1.tar.gz. After downgrading both of these packages, I still experienced the focus issues as previously described.

2. I rebuilt gaim using a tar ball of the gaim 2.0.0beta3 sources as downloaded from source forge about two weeks ago. This particular instance of gaim worked under Dapper, and interestingly, when I built it under edgy, it resolved the buddy list focus issue. Edgy is purportedly shipping the same version of gaim but for whatever reason, the problem occurs with the version that's bundled, and goes away if I rebuild from the source tar ball.

Hi All:

I was finally able to do some testing with this.  I'll confirm that none
of these are Orca bugs.  We do care, however, about the overall
accessibility of the platform.  So, we'll dig into these problems more
and follow up with the appropriate teams.

My experiences show that GAIM will come up without the buddy list and
you need to press the gaim icon in the panel to show it.  I've tried
various ways to get to the icon from the keyboard, but I cannot seem to
do so (BAD for people who cannot use the mouse).  So...I resorted to
clicking on it, which brings up a menu allowing me to show the buddy

Once I was able to make the buddy list visible, I found that Orca seemed
to do just fine with it.

Note that this seems to be only with GAIM 2.0.0beta versus GAIM 1.5.1.

I found that something broke with gnome-terminal's implementation of
getTextAtOffset: it's giving us very wrong and very incorrect values for
GNOME 2.15.90 versus GNOME 2.14.  As such, it's difficult to know where
text is on the screen as well as getting the text for the line where the
cursor is.  We will dig into this more this week and file a bug with the
appropriate component (gnome-terminal, vte, ...) when we learn more.

I dug into this some more, and there appears to be some binary
incompatibility between the AT-SPI implementation used by OOo and what
is in GNOME 2.15.90.  We've brought this to the OOo team's attention and
will be following up more with them this week.  Note that this may or
may not be an OOo problem (e.g., it could be an inadvertent AT-SPI
