Is the issue that you click on a folder and the screen goes black?
If so, this happens when there are more than 8 items in a folder. I think hitting the home button or sleeping and waking the phone will get you back to your home screen; can't remember for sure though.
There is no way around this I know of as it is an iconoclasm bug. This is the reason I stopped using iconoclasm. Perhaps using something like FolderEnhancer or Infinifolders corrects for this, but I'm not sure.
Good luck!
