BUG: problems when creating new package with diagram

[fausto bertoli]

We use EA 17
we have installed C4 model downlaod from your website (built by lieber)
We try to create a package with a deployment diagram
EA create the package and answer with a dialog box with this message "Encountered an improper argument"
We enter ok and the model builder dialog appear with focus on diagram builder
we select UML structural
and the same error dialog appear again
we can do it forever...
if we activate the model builder tab we can select deplyment diagrams to create but...
If we do this we are not able to activate the reltaed toolbar we find inside the toolbar options .. but not founded
How can we insert deployment diagrams and use the related toobox?
regards.

I discovered why the message box with error appeared.
Most of the UML technologies were deselected within the MDG technology dialog.
If I enable Core UML all works.
However I suggest to convert the criptic error message in something more self explained
