This only means that GEOM_LABEL detected an ext2fs-compatible file
system with an empty label (or the label might be "/"?). I don't know if
this particular thing would cause your error, but you might want to try
and change the label on the ext2/3 file system to something using only
alphanumeric characters (I think tune2fs -L can do that).

If it turns out that geom_label is causing your problem, then yes, you
should file it.
