NullReferenceException after adding a comment to a component diagram (#115)

(Bug Reports)

I added a comment to my component diagram and then tried to edit the comment text. This caused an exception. "Send Report" did not work, so I'm posting the exception here.

I got the following exception:

System.Reflection.TargetInvocationException: Ein Aufrufziel hat einen Ausnahmefehler verursacht. ---> System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.

I cannot reproduce this problem.

Do you encounter this problem regularly or it was a single case?

Anyway, I will continue to analyze this problem.

I did not see the problem again.
