Sorry for the delay, yes, it is still an issue with the final maverick. To reproduce this, I took a second disk and created a partition starting on sector 1 instead of 63 or 2048. I then installed to a root fs on the first disk but told the installer to install grub on the second disk, which predictably failed, causing the broken dialog box to appear.
