Oh, BTW I can make Vue crash every few minutes if I want (but only in heavy scenes with many polygones, many objects)in doing the biggest error:-) If I don't wait until Vue has finished the task I just asked for, but ask another task immediately while Vue is working on the previous. And as I don't understand why Vue needs some time to do the task, I just ask it twice or more and then maybe even another one. LOL This may be great with a 4 Giga machine, but not with a 2.8 or less:-) Can this be a reason for your crashes?
