Export to csv with blank row error apex 4.0.2

Question

In a tabular form when I use the export to csv, it return a csv file and the data is fine but there is a blank row between the header and the first row of data.
It happens in the 4.0.2 release. I used the 3.1.2 release before and it worked perfect.
It is a bug? any idea to fix it? I want to avoid the manual export because it's a complex query with agrupation levels.
Thank you!

An easy solution to formatting columns as text in Excel exporting (even handles leading zeros properly). In the report SQL do the following code:
For Interactive reports:
decode(:REQUEST,'CSV','="'||your_column||'"',your_column) your_column_name,
For Standard reports:
decode(INSTR(NVL(:REQUEST,'FOO'),'FLOW_EXCEL'),0,your_column,'="'||your_column||'"') your_column_name,
Interactive report example
select address1,
address2,
city,
state,
decode(:REQUEST,'CSV','="'||zip_code||'"',zip_code) zipcode
from your_table
Standard report example
select address1,
address2,
city,
state,
decode(INSTR(NVL(:REQUEST,'FOO'),'FLOW_EXCEL'),0,zip_code,'="'||zip_code||'"') zipcode
from your_table
This will work without modification if users modify and save an interactive report as well.
