When doing application profiling, when one double-click (select) specific functions in the overview, an editor view is 
supposed to show up with extra horizontal bars showing resource consumption.

This view would not be generated, just a gray editor view with an error
(more...) button.

Reinstalling did not work, copying the workspace from another machine that is working also not work.

However a comparable view for code coverage did work, even though that is probably not related.

Any ideas what is causing this?
