Column is lost when moved out of range, no undo possible

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a new project with the following (tab-separated) text in the 
clipboard:
Column1 Column2
v1  v2
v3  v4

2. Parse data as "CSV / TSV / separator-based files", with default settings.

3. In "Undo / Redo", apply the following:
[
  {
    "op": "core/column-move",
    "description": "Move column Column1 to position 4",
    "columnName": "Column1",
    "index": 4
  }
]

What is the expected output?
The expected result should be either an error or Column1 moving to the right of 
Column2 and a new operation being registered in "Undo / Redo".

What do you see instead?
Instead, no error is signaled, Column1 disappears, and no new operation is 
registered in "Undo / Redo".

What version of Google Refine are you using?
2.5

What operating system and browser are you using?
Mac OS X 10.7.4
Chrome 21.0.1180.75

Is this problem specific to the type of browser you're using or it happens
in all the browsers you tried?
I tried Safari 6.0 (7536.25), with the same results.

Thanks for the detailed step-by-step.  Sorry about the problem.  Increasing 
priority since it represents potential data loss.

Where in the GUI did you do the manipulation which resulted in that JSON for 
the operation?  I'm not seeing anything which would allow you to move a column 
out of range.
