Short story is... Bog-standard Wordpress setup. Home page and dashboard work fine. Trying to navigate to any linked page causes a sigsev in apache, which backtraces to the above. I upgraded from Ubuntu's current 5.5.9 to 5.5.16 in the PPA at https://launchpad.net/~ondrej/+archive/ubuntu/php5. No change.
