segfaulting pdf
SUMMARY
I have a few pdfs on which okular crashes with a segfault.
All of them are from the same source (Inria), I tried random other pdfs which
all worked fine.
Other programs (the other pdfs always worked fine):
- evince opens them without issue
- the calibre ebook viewer fails to open and says "failed to initialize plugin
DeDRM [some trace] UnicodeEncodeError: 'utf-8' codec can't encode character
'\udc90' in position 6: surrogates not allowed"
- libreoffice says "the signature is OK but the certificate could not be
validated", clicking "show signatures" makes it complain about non existing
XXXX.tmp files in the pdf's directory
So the issue seems linked to signatures but I don't know enough about how that
stuff works to be sure.
STEPS TO REPRODUCE
1. open attached file
2. witness crash
OBSERVED RESULT
crash
EXPECTED RESULT
view pdf
