I think you found a bug :--(

The code that checks if a handler should be applied only does the namespace relacing for "simple" handlers, not for handlers with a path. I will have a look at this and should have a fixed version by tomorrow.

Then maybe this will be the final straw and I will start working on cleaning up the code that triggers handlers, which has grown quite a bit in the last few years and is now quite a mess.

Thanks
