Window Management: 'ghost' columns

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open any two windows and place one in the second column (by moving it right, 
not by moving the other left) (if unable to reproduce, try with sakura, gvim, 
xev, or xterm)
2. Close the window in the first column.  The second-column window should now 
fill the whole screen (as expected)
3. Move the remaining window to the floating layer and back to the managed 
layer.  It should now be back in its position in the second column, with empty 
space where the first-column window was after step 1

What is the expected result? What do you see instead?
Expected: The remaining window fills the entire screen, as after step 2
Actual: The remaining window acts as if the first-column window that was closed 
in step 2 were still there, and only occupies the right portion of the screen
