Test example

1) Create a new Excel file.
2) Remane sheet 1 as "a & b" (without quotes)
4) Put some value in first cell
3) Go to sheet 2 and link the first cell to first cell of sheet 1 (now named as
"a & b") (='a & b'!A1)
4) Save (as .xlsx / MS Excel 2010) and close Excel
5) Reopen excel and load the saved file
6) It will display a "broken link error" and the first sheet will now be named
as "a & b" whereas first cell of second sheet still links to ='a & b'!A1
(correct)

It seems a escape / unescape issue while opening the .xlsx. I'm pretty sure the
issue is while opening, not sving, as the same issue occurs if you create the
file as described above in windows and try to open in linux with wine.

The issue is occurring since wine 1.5. It wasn't in the past.

I've attached the test .xlsx file
