Create a new Writer or Calc document. Insert data from the URL below into the
document: 

There are 2 ways to do this:

1. In Writer choose "Insert - File..." (but make sure "Tools - Options -
StarOffice - General - Use StarOffice Dialogs" is checked). 

or, 2. In Calc choose "Insert - Link to external data...", paste the URL into
the URL text box and press Enter. (but make sure that "...Use StarOffice
Dialogs" is NOT checked).

After a while OOo tells you: "Daten konnten nicht über das Internet gelesen
werden. Serverfehlermeldung: Error reading response headers: Line too long."

What's most strange, if you replace "Spreadsheet" by "Word+processor" in the
URL, it works. In Writer it also works if you use the operating system File Open
dialog. And, of course, the URL below can be loaded without any modification by
Firefox.
