Opera causes CF to throw error?

Working on a site, decided to fire up Opera just for kicks. Getting a cfdump tag error saying that it needs the var attribute.

There’s no way a browser can cause an application server to crash, right? Site works fine with safari and firefox. IE too.

right

I have never seen that happen before, were you able to get this figured out?

nope. Gave up. Don’t get much (if any) opera traffic on the site that I’m building this for, so it’s not a mission critical error, just something that TOTALLY stumped me.
