[poppler] Freeing a PopplerDocument object

[ANTONI SILVESTRE PADROS]

Hi, I am sure I am missing something really obvious but I cannot find any way to explicitly free or "close" a PopplerDocument created with the function poppler_document_new_from_file.

The thing is that I am reading files from a USB pendrive and after I have read a PDF from it there's no way unmounting the pendrive without closing the application.

Any help will be greatly appreaciated.

Thanks

Toni
