Does the minidump happen right at the start of the map, or does it happen during the game?
If it happens at the start, you probably just have to port your files to the newer version.
If it doesn't happen until the game is in progress, then I would suspect an AI minidump. Maybe the AI player is scripted to use abilities based on planetModuleRoleType (it does expect the structure with planetModuleRoleType "REPAIRPLATFORM" to be able to repair ships, after all), then dumps out when it can't.
I know for a fact that the AI uses roletypes for building and using ships...and if it can't find one of the roletypes in its build lists it will minidump. What could be happening is that it once it builds the building with planetModuleRoleType "REPAIRPLATFORM", it tries to tell its platform to repair one of its ships and then can't because the ability it is scripted to use isn't there anymore.
