Ewww .... well, not sure what to tell you about that.

I am using e2fsprogs-1.41.6.sun1-0suse ... and I know that is old.

I was going to say that I don't know if revving up e2fsprogs is okay, but
I see that Andreas already answered that one.  I can't be 100% sure that
upgrading e2fsprogs _will_ solve your problem, but I think it's worth
a shot.
