The errors you mention are the effect of filesystem corruption. Dirty FAT is mounted ro, as any damaged filesystem (though different than ext2/3 you will not see it's mounted ro). To repair it unmount the fs first using sudo umount /dev/sda1 (assuming it's /dev/sda1) and do not use eject function of GNOME. Then repair the fs with dosfsck -r /dev/sda1.
It's probably not best place to provide not exactly bug relaed discussion here, but as the corruption is an unavoidable effect of the bug, it's worth mention here. Hope it helps.
