Just to make sure we are all talking about the same thing, mostly for the benefit of girao.
I think this crash is talking about when you design a new trim, then press the build button.
There is a separate crash/series of crashes related to the "Design Body" Screen. (the screen you get by pressing the design body button during vehicle design).
I just created a thread on that crash and those related issues.
The crash you talked about related to painting a vehicle sounded like one of these, rather than a trim related crash.
