This sounds, to me, like it might be related to the External uSD Card being mounted as Read-Only. I use Koreader, so it is easy to remount the /mnt/sd as Read-Write, by adding the following to the launching script:
# remount external SD as RW
mount -o remount,rw /mnt/sd
Don't know how you would do that for nickel, without a hack/patch, unless you were using Tshering's "Kobo Start Menu".
Luck;
