YAC (Yet Another Crash): deleting an item property

[kinook]

Thanks. I couldn't reproduce any errors when renaming an attribute, but I was able to reproduce that error by:
1) Creating an attribute
2) Assigning it to a form
3) Creating an item that used the form
4) Populating the attribute on the form
5) While still at the item, deleting the attribute
6) Switching away from the item or closing the database

After the error was displayed, I could still exit UR (File | Exit) normally and the problem went away on restarting UR. This will be fixed in the next relesae. For now, you can avoid this problem by a) not deleting an attribute when a form is showing that attribute (select a non-form item first) or b) removing the attribute from the form before deleting the attribute.
