dashboard columns not working

[solsikkehaven]

when changing dashboard screen options from 2 columns to 1 or 3 or 4 and then changing back to 2 columns, gives you 2 columns, but column 2 is empty, all dashboard items are in column 1.

using latest 3.0 rc3 (15260) in multi site mode

just checked to see if this is some sort of cache problem with my local computer, but no. tested in firefox and safari - same problem.
