bug#59292: libreoffice password protection doesn't work

[Maxim Cournoyer]

Hi,

When password-protecting (encrypting) a file with LibreOffice, it fails
silently, leaving the file unprotected (!).

Reproducer:

1. Launch Calc with 'libreoffice --calc'.
2. Input something in the first cell.
3. Select File -> Save As.  At the bottom left of the dialog box, make
sure to tick the "Save with password" box.  Give it a name,
e.g. very-secret.ods, then click on "Save".
4. Enter a dummy password, such as 1234.
5. Quit LibreOffice Calc.

6. Open the assumed protected file, with 'libreoffice --calc
very-secret.ods'.  Notice the file is open without any password.

No output is printed at the console, and if you have an truly
password-encrypted file, it won't be able to open it.
