Debug file with perhaps show why happening the problem if --disable main-window option is used

Dear Developers,

When accessible login is enabled with screen reader support, and gdm login screen is presented the screen, Orca main window is displaying the screen my system.
In source code directory orca-autostart.desktop.in file containing following command line:
exec=orca --no-setup --disable main-window --disable splash-window --disable magnifier --enable speech --enable braille

The interesting result, when I quit Orca after I logged in, and run terminal this command, Orca main window is displaying the screen, perhaps disable main-window option is not working?
If I remember right, Before yesterday I not see this issue, and hopefuly this issue is only presenting my system.
I Using Ubuntu Lucid, and latest Orca git master version.
My /usr/share/gdm/autostart/LoginWindow/orca-screen-reader.desktop file is following (factory Ubuntu filled):
[Desktop Entry]
Name=Orca Screen Reader
