Hi, can you please post a test case built using jsfiddle.net? The code snippet you provided isn't enough since it's not even clear what "this" is.

I simplify test case...

Confirmed in Opera 11.01 on Windows; I simplified the test case a bit and tried a few permutations:

I think this may have been fixed in Opera 11.1. Can you confirm?

Why is this not higher priority? Having simple selectors fail seems like a blocker.

+1, Seems like a bug, should be fixed

+1, weird

This seems to be an issue in Opera itself... It isn't throwing an exception for Unknown psuedo class when the non-standard :selected is on the right side of the comma...

-1, As discussed in the Monday meeting, this is an Opera bug so I think we should close it wontfix and let the Operatics do their thing.

+0, I fear what's actually happening here. Opera's querySelectorAll is really bad.

Isn't one of the main purposes of jQuery to overcome browser bugs?

+0, If this is an opera bug and only affects pseudoselectors, we might have to suck it up. Seems like it could be high cost, low reward...and there could be a fixed Opera, and we know how Opera users are (they love updating).

This was an Opera bug, but it's been fixed in Presto since reported. The problem was "querySelectorAll does not throw for an unsupported pseudo-class part of selector if there is a valid part first."

So, either wait for your users to upgrade to whatever version the fix gets integrated (12? dunno), or don't use custom non-QSA selectors.
