I run a compact double crankset with a triple derailleur. Sometimes, when the cable tension drops even slightly, that chain wedge thing will happen. It happens on DH's bike too, and he's running a compact double with a double derailleur. In fact, it happened on his bike on today's ride. Half a turn on the downtube barrel adjuster, and problem solved.
I'd double-check the tension before doing anything else...
Good luck!

Unlike some measurements on a bici, tube and clamp diameter is a true measurement. Just put a caliper on it.
Can't help you with the rest of it, but size is easy.Speed comes from what you put behind you. - Judi Ketteler

I seem to be seeing a bolt head where there usually wouldn't be one. Thus I think you have a "braze on" style mounting for your FD. But it also looks like you have a clamp. So - perhaps you have a clamped on "braze on" mount? If so, this digression is moot because you could substitute the whole thing with a clamp style FD.
