Example pdf file with a single annotation

The attached sample file contains nothing but a single freetext annotation.  It
was created using LaTeX and the pdfcomment package.

1) Open the file in Okular
2) Click on the annotation
3) Press F5 to reload the file
4) -> Okular segfaults reproducibly

This happens with the current git master.  The backtrace is

Thread 1 "okular" received signal SIGSEGV, Segmentation fault.
