So, I did a search and turned up a number of topics, among them:
http://wordpress.org/support/topic/360133
http://wordpress.org/support/topic/315131
http://wordpress.org/support/topic/283773
http://wordpress.org/support/topic/312040
But none of them resolved the problem. In the meantime I can just use the_excerpt() instead of the_content() (which might be safer for the other users making posts regardless), but I'm curious why it might not be working.
Thanks! Link is http://teknikor.com/content/news/, appropriate template follows (not mine originally, but I'm comfortable editing it).
