OK: I've never tried this myself ...
My system uses Ubuntu Dapper and OOo 2.0. The floppy is block-special-device: /dev/fd0 which is mounted to /media/floppy0 (/floppy is an unusual mountpoint - you should check this) ... I can read the files in the floppy but "save as" generates the error you report.
I note that the "save" option is greyed out - so I suspect a permissions issue.
ls -la /media shows that root is the owner and only root can write to the floppy.
So I would check your permissions if I were you.
Usually I would mount a floppy in cli using $ mount /media/floppy ... however, mount couldn't autodetect the file system type so I was forced to use sudo mount -t vfat /media/floppy which worked fine... only it set the owner of the floppy to "root" instead of my user.
I edited /etc/fstab so the fs in the fd0 line read "vfat" instead of "auto", and remounted the floppy as a normal user. This time, save-as worked fine.
Possibly you mounted the floppy from commandline as root?
