My customer has a document with some tagged text. Applied to the tagged text is a paragraph style that contains a nested line style. This document crashes during conversions. This crash occurs even when all conversion code in my plug-in is commented out. It also crashes when the plug-in version number remains the same, but the document converts from CS4 to CS5. The crash does not occur when the nested line style is removed. I'm hoping someone might have an idea of what might be happening.
If it helps, here's an ASSERT that occurs when converting from CS4 to CS5:
AttributeBossListIterator::CreateID() - Cannot have invalid ID.
