Bug 141277

Version:           1.5.6 (using KDE KDE 3.5.6)
Installed from:    Ubuntu Packages

Tested on an empty user account.

I open umbrello, create a new use case diagram by the "Diagram" menu.

First, the canvas is frozen and I can't add anyone element. I select the default "class diagram" in the tree on the left, and the re-select the use case diagram previously created. Now, I can add an actor and a note. If I try to add an association between the actor and the note, umbrello always crashes.

Partial backtrace :
(no debugging symbols found)
