Description gopher292 2006-04-27 21:04:40 UTC 
Whenever you open a blank .csv document with OpenOffice, it outputs 1536 bytes
of excel header to the file.

(In response to fst:)
To reproduce the error on a Windows computer:

- Right click in a folder listing and select "New > Text Document".
- Name the file using a .csv extension.
- Open the file with Calc.
- Click either "OK" or "Cancel" in the Filter Selection Dialog.

The file is now 1536 bytes long and the contents (when opened in Notepad) appear
to be the same as Microsoft Excel's header.

I am using an AMD-based computer running Windows XP Home with SP2.

Hi Eike,

strange thing and I think it's your construction site.

Looks like either an uninitialized memory area or a storage file header.
Comment 6 Martin Hollmichel 2007-11-09 16:51:57 UTC 
change target from 2.x to 3.x according to
http://wiki.services.openoffice.org/wiki/Target_3x

This actually does not only happen in Calc but also in Writer if Text encoded is selected. I assume that the filter detection tries to open an OLE storage file but instead of only reading the file it creates the storage if the file is empty. The SvStream read in Calc starts already with an actual buffer length of 1536 bytes.. the 3rd "sector" even has a "Root Entry".
