Caused by

Which is only intended to be run once, but the nested FixedDocument causes it to run twice.

hmm, I would sat the document is buggy, the spec says the FixedDocument element contains one or more PageContent elements. Anyway, we shouldn't crash even for buggy documents, I'll look at it.

This should be fixed in current git master now. Thanks for reporting.
