I know there are differences in Selenium behavior between browsers and OSes. But was wondering if anyone has noticed issues with Selenium RC across language bindings (that is using same test flow, same locators, but different languages).

I just recently noticed case where locator and thus test worked with Python binding but failed in PHPUnit / PHP binding for same exact locator.

But I guess this is less noticeable as few people switch language bindings for a test in Selenium.
