I'm seeing that too.  But the unconfirmed namecoin dust is apparently being added to the right-hand figure.

I like the new dashboard screen, but I'd prefer all the reward figures to have a fixed number of digits after the decimal point, including any least significant zeros.  I have a mild panic attack when (for example) 0,00821476 becomes 0,0086147 and for just one horrible moment I think it's been nobbled!

Edit: Also, the 'Time since' does not update without a full page refresh, and the recent hash rate graph is broken – only showing the top left one-sixth.
