EDS Database choking?

An interesting problem I am haveing now....

Below is a partial trace of code that happened when
db_delete_table( ) was called.

The table does exist I have confirmed this by reading 
the database.

line 456 in database.e is what fails

456.    safe_seek(addr-4)
457.    put4(size) -- in case size was not updated by db_free()

it looks to me that addr is 0 when I get here so It must be a bug
in database.e "Robert"?

or,

Is this happening because the last table is what I'm deleting
and it has 0 keys or data attached to it?

C:\EUPHORIA\include\file.e:29 in function seek() 
type_check failure, pos is -4 
    fn = 3
    pos = -4

    pos = -4

    addr = 0
    free_count = 5
    remaining = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
0,0,0,0,0}
