java.lang.UnsupportedOperationException: Position.start upon certain navigation operations
The plug-in frequently causes a java.lang.UnsupportedOperationException to be thrown, often when doing certain types of navigation operations. I can't yet repeat on demand -- I'll update the ticket when I can -- but I wanted you to have the stack trace in the interim.

I came across this bug too and am able to reproduce it consistently in one particular place in the scala source code:
1) In ScalaToggleBreakpointAdapter, put the caret on "ToggleBreakPointAdapter" (which ScalaToggleBreakpointAdapter extends)
2a) Punch "F3" to navigate to that class and you will get this error
2b) (might be mac specific) If you bring another application to the foreground and navigate back, you will get an endless stream of these error dialogs, each supplanting the last when you click "OK", until you close the open editor.
