 If a vizkit plugin produces an exception one gets an stack trace
 like this :
 vizkit.rb[WARN]: could not read on

 At least for me it was not obvious that this error actually originated
 from an plugin.
 Is there a way to produce a better stack trace in these cases ?
 My preferred solution would be an error like :
 Plugin 'FooViz' threw exception : "Foo error in FooViz"

 So goods of ruby, any ideas ?
