My guess would be an unbalanced set of q and Q commands in the document stream causing this. But I've been wrong before! @iGrog, can you please send the offending PDF to bhuisman at greywyvern dot com? I'd appreciate a look. Thanks.

@GreyWyvern Thanks. PDF was sent to your email

Thanks! It turns out this PDF has an inline image object which is fouling up the parser in formatContent(). The parser removes strings, but it should be removing these inline images too. I'll work on a solution for this.

@iGrog can you verify that the code from #693 resolves your issues? I've been using the "fixed" code for several weeks now and haven't had any issues myself, so I'd like to switch it out from being a draft. Thanks!

@GreyWyvern I've checked parsing dozens of PDF files, and all of them succeeded (including those that used to crash due to NRE). Looks like it's working :) Thank you!
