by Harald Wallus <wallus at results-hannover.de>:

I have a crash on my umbrello1.2-beta (tar-ball of 11/5/03) on SuSE9.0 .
open a implemeted class,
open a operation,
open a property,
try to delete last  argument,
bang.

Reproducable.

Sebastian Stein <seb.stein at hpfsc.de>:
1. create a class with an operation
2. add 2 parameters to the operation
3. open operation tab in class property dialog
4. delete (with the button) the last operation -> crash
