[Pharo-dev] Pharo3 Theme not really active in CI built images

When I download a fresh Pharo3.0 Latest update: #30558 from CI the menues look awfull (dark gray) since I think the theme is not correctly initialized. Switching the theme or evaluating Pharo3Theme beCurrent fixes this easily. So there is no method to change, just some code to run. So I dont think this can be fixed with a metacello slice. How can we run the above "do it" to correct the images? Thx T.
