Indeed, I suspect we have more uninitialised class members that need
sorting too, we have quite a few reported by coverity. Some of course
aren't essential, but I almost prefer initialising everything ;-)

But this one is indeed an uninitialised access in Capture::requestComplete.

I guess we could add a fixes tag, but it doesn't really matter ;-)
There's no backporting happening here ;-)
