[Uml-devel] crash when creating attribute

Sun Mar 9 13:21:03 UTC 2003

hi all,
I have a bug here, and am not sure if it's thanks to some of the 
diagram/dialog code I am doing or not.
I really dont see why my code could be interfering, but I just happend to 
discover it after doing some changes to my dialog pages.

could you please test and see if you can reproduce it?
1. start umbrello
2. create a class in the default diagram
3. right click on the listview->properties
4. switch to the attributes page and click new
5. accept the defaults (name and everything) and just click ok
6. you get a nice dump:
