It looks like the source location of a program element is unexpectedly null at this point.  I'm not sure why this is.  I added a null check and also will add an entry to the log when this happens.

Please update to the latest dev version and try again.  Keep an eye on your error log when you open the visualizer.  Let me know if you see any relevant entries, particularly ones that are prefixed with "Bug 324706".

You an get the latest dev snapshot from this update site:

This fix is only available for 3.6 right now, but if you are on 3.5 I can back port it.
