I had what looks like the same crash yesterday, on a laptop with 1 Gig RAM and 2 Gig swap.
Crashed after asking permission to delete obsolete packages, ate swap space rapidly then out of memory.
System appeared to reboot OK afterward, though wireless networking was broken by the upgrade.
What are the options for moving forward on this machine? Can I finish the upgrade somehow, or is the OS scrambled?

Of course title should be Kubuntu 6.10 to 7.04 upgrade crashed.

thanks for reporting this. This is actually a known issue that is filed as bug 107188.

Paul, most people are finding that you should be able to reboot just fine and the system will be operational. It seems to be the case that the system installs correctly and just fails in the final clean up stages which you can do manually. Check the thread for bug 107188 for more details.

thanks,
Richard
