A suggestion, I do not know how to write code, but I am pretty strong in observation. Do this, Allow users to go into safe mode in Ubantu and make adjustments to evolution mail. I did not find a way to get into safe mode, perhaps someone else knows how to do this. If there is a program, I guarantee you, there exist a safe mode as well as a way to reboot.
