[orca-list] In Ubuntu 10.04, when Orca is running, impossible to make USB startup disk with usb-creator-gtk application

[Hammer Attila <hammera pickup hu>]

Dear List,

I see a very disturb problem because I have got a netbook, I would like 
ask a hint what correct accessibility related component producing 
following possible critical bug:
In Ubuntu 10.04, when I try make an USB startup disk with 
usb-creator-gtk application and Orca running, after I clicking the make 
startup disk button, my desktop is full unresponsive, Orca is full 
frozen, and the USB startup disk is does'nt maked.
If Orca is not running before I clicking the make startup disk button 
and does'nt run entire startup disk make process, usb-creator-gtk 
application is correct make the USB startup disk.
Few weeks ago in Vinux mailing list we detect this problem is possible 
happening because at-spi registri is crash, but I impossible send the 
important crash related data with bugreport, because nothing public data 
present my system with related this problem.
Unfortunately, this problem is always reproducable my machine when Orca 
is running.
When I look in Orca debug.out file what happening after I clicking make 
startup disk button, I see following information after cancel button 
speech output spokening:
SPEECH OUTPUT: 'Cancel button. Alt c'
^^^^^ PROCESS OBJECT EVENT focus: ^^^^^

---------> QUEUEING EVENT object:children-changed:remove
---------> QUEUEING EVENT object:children-changed:remove
Entire remaining debug.out part containing this me unknown lines. :-(:-(

I do a bugreport with Ubuntu bug tracker with at-spi package, but 
because missing any important data, this bugreport of course is not enough:

Joanmarie, your openion this problem is an Orca related bug, or another 
accessibility related component producing the problem?
My system is full uptodated.

If anybody try reproduce this problem, do following steps:
1. If you using Ubuntu 10.04, try insert an Ubuntu CD rom and attach an 
USB pendrive.
2. When Orca is running, launch system/administration/make startup disk 
application, or use usb-creator-gtk command in gnome-terminal
3. When you click the make startup disk button, your desktop is full 
unresponsive, Orca is does'nt talking, and impossible to restart.
If you does'nt have an Ubuntu CD, but have downloaded Ubuntu CD image 
file, use usb-creator-gtk -i isoname command when you would like launch 
the make startup disk application in gnome-terminal, for example:
usb-creator-gtk -i lucid-desktop-i386.iso

Thank you the possible helps and hints,

Attila
