[Pharo-dev] Are all SLICEs self-contained?

If not, how do I know if a SLICE depends on other SLICEs? For example loading https://pharo.fogbugz.com/f/cases/edit/11282/Removal-DependentFields-referen... using Monticello hangs the image and cannot interrupt with Alt+. Do I need to load another SLICE before? Cheers, Hernán
