[poppler] [Poppler]A bug in poppler-private.cc?

[cobra.yu]

    Take poppler_qt4viewer for example, it creates and checks the "newdoc" before deleting the old "m_doc". That means, count++ before count--.
    But in my application, every PDF document is converted into QImages separately, so count-- happens before count++, and that's the problem.

I will need a backtrace of your code since globalParams is guaranteed to be 
created after  DocumentData::init which is the first thing that gets done 
while trying to load a document so i can not see at all how your globalParams 
pointer can be invalid.
