Lee, I tried pynguin-0.12.zip on Windows7, python 2.7, PyQt 4.8.4 32bit, and I could run "go()" many times without any crashes or warnings. However, there appears to be no "tournament" function.
One advise, if I may say so: The chance of finding someone who would be willing to debugg your entire project is slim. On a mailing list such as this one, the best way is to reduce the problem to a self contained, minimum size test case which reproduces the bug.
