Joe,
I commented on your bug. I don't think its related to the templating security fix at all. That just changes how variables are substituted within translation message keys. Its a pretty obscure issue.
Basically the statement_name passed into template::paginator::create is an empty string and we need to track down why that is.
If possible more interactive debugging assistance is available almost 24 hours a day from #openacs on irc.freenode.net.
