Description Jose Vilmar Estacio de Souza 2012-01-25 23:53:52 UTC

I am trying to Access my homebank account using latest orca from master, ubuntu 11.10 and FF 7.0.1
Using down arrow to scroll in the document and suddenly orca stucks in a line announcing only the word grater, even if I press down arrow many times.

At this time, if I press right arrow, orca stays completely mute and I need to kill firefox.
After kill FF, orca returns to its normal state.
Unfortunately I can not give the url of the page because it will require my login account. I'll try to find a page where this can be reproduced.

In the debug I found the following trace back:
vvvvv PROCESS <ENUM ATSPI_KEY_PRESSED_EVENT OF TYPE EVENTTYPE> 'Right' (114) vvvvv

Traceback (most recent call last):

Comment 1 Jose Vilmar Estacio de Souza 2012-01-26 01:26:56 UTC

The word read by orca when I press the down key is 'grayed' and not 'grater' as posted in the description.

I found a public page where the problem can be reproduced.
http://www.noobslab.com/2011/12/install-firefox-9-on-ubuntu.html

Try scroll in that page using down arrow until you hear grayed and then press right arrow.

Orca freezes completely and I need to kill only firefox.

I'll paste the trace when accessing that page.
vvvvv PROCESS <ENUM ATSPI_KEY_PRESSED_EVENT OF TYPE EVENTTYPE> 'Right' (114) vvvvv

I forgot to mention in comment #1 that I used version 9.0.1 of firefox.

Comment 3 Jose Vilmar Estacio de Souza 2012-01-27 13:53:24 UTC

Another  link where the problem can be reproduced.

Comment 4 Joanmarie Diggs (IRC: joanie) 2012-01-27 16:36:24 UTC

I see the getting stuck, but not the tracebacks. I am running AT-SPI2 from master and am guessing that is making the difference. Also note that in terms of the code in question, we are specifically/intentionally raising the exception. Anyhoo, the "bad things happening around 'grayed' Gecko objects" is bug 665820.

The trace happens after you press the right arrow.
After press the right arrow orca stays mute.
