From a quick sketch, it seems that is not convex. Is that correct? You can use concave collision shapes, but you need to decompose it into convex shapes and add them separately.

Also, if possible, give them a little bit of overlap so that you don't get "cracks" between the polys that a line segment could slip into.

Yeah, it's a square with a bit sticking out - so it isn't convex. Thanks for clearing that up :D
