While you select the "Generalization arrow" tool and then right-click on an item to duplicate it, Umbrello crashes and stops.
Can you provide the following informations: 1. Are you using 32 or 64-bit variant ? 2. Can you describe exactly what you did after starting umbrello to be able to reproduce this crash ?
BTW: Is this issue reproducable with 2.21.80 too ?
1 - It is the 32bits version 2 - On an existing project, on a class diagramm: - select "Generalization" in toolbar - Then rightclick on a class object to open contextual menu - Select Duplicate in the contextual menu - Enjoy a crash ! 3 - I've not tried it on version 2.21.80
Could not reproduce with two simple classes with a the recent version 2.24.3. If you can reproduce this issue with 2.24.3 please append a related test case.
