Debug file with show possible why happening this problem

Dear Developers,

In Orca committed following setting change to prewent Openoffice.org crashing. The changed new setting is following:
synchronousToolkits     = ['VCL']
Original prewious setting is following:
synchronousToolkits     = []

The problem is following:
When I using this new setting, and selecting text with Openoffice.org Writer and Libreoffice Writer, Orca does'nt spokening the selected state if I using Shift+Down arrow keypress to select a line. If I unselecting a line, first Orca spokening right the "unselected" text, but if I unselecting for example more lines, Orca spokening two time the "unselected" texts.
I tested this problem with original Ubuntu Lucid packaged Openoffice.org version (3.2 version) and Libreoffice 3.3 version.
Reproducation step if you using this new setting:
1. Launch Openoffice.org or Libreoffice Writer.
2. Write three lines with single lines and close last line with an Enter key.
3. Go to top of the file, and try select three lines. You not will be hear the "selected" message if you press Shift+Down arrow key combination.
4. When you selected all lines, try pressing more time the Shift+Up arrow key. First line unselecting you will be hear one time the "unselected" text, but another lines unselecting you will be hear duplicated the "unselected" text spokening.

If I restoring this setting with orca-customizations.py file with original value, this problem is not happening, but Openoffice.org Writer is crash lot of time. Have possibility to keep this new changed setting, but fixing this problem?

I attached a debug.out file with show this test steps happening.
