It might be a bug in POI. calcChain.xml references formula cells and if a reference becomes invalid, e.g. cell deleted, then PowerPoint is not happy. There is some support in XSSF to keep calcChain.xml in sync but it doesn't cover all possible cases.
Can you create a bug in Bugzilla and upload the input workbook and Java code that generates problematic contents? Without a reproducible test case we can't do much to help you.
