Checked with the latest development build

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

1. Have a linked pdf file
   (my pdf file was 838 kb)
2. Have bibliographic data
3. Write XMP metadata to pdf via Tools > write XMP metadata to PDF files (F6)

What happens:

• Trying to open this pdf file with a pdf reader (e.g. foxit reader / pdf xchange) shows the pdf has no pages anymore.
• The size of the pdf shrinks to ~ 4kb
