Bug: accidentally wrong connection

Hi guys, I think I found a sort of bug.

I accidentally connected the OSM-Data to a XML-input and it gave me this error.

You can klick on OK, but it will just open the the error message again. Only solution here is to go to the Task Manager and end Rhino there...

I'm using Rhino SR5 (in German, as you can see in the error message) with the current Grasshopper Release 0.9.0056 and the current Elk.
