As I noted in the thread I linked to, Photoscape does not crash on my system with native gdiplus, but I am on openSUSE 11.1. Are you using the Ubuntu Wine packages, or did you compile Wine yourself? If you are using the packages, the next logical step is to try compiling Wine yourself and see if Photoscape has the same problem. If it doesn't, then the problem is in the Ubuntu packages and a bug should be filed with Ubuntu.
