I've got a well-formatted print document including paragraph styles mapped to tags that crashes when I attempt to expoert as an ePub. The problem appears to be the formatted text because when I copy it out and paste into a new document it happens, but when I strip all formatting by saving as a *.txt document and import, it exports fine.
If I am unable to start from a formatted document, this feature is broken. My client's files are produced first for a print magazine, then an iPad app, and now to produce HTML and CSS via an ePub export.
Here is the top of the error log. Does any of it provide hints? Any suggestions are welcome.
