Comment 1 Robby Stephenson 2019-05-13 13:48:00 UTC 
Can you add what version of libexempi you have? For Fedora 29, I'm assuming 2.4.5?

Are you able to test those same PDF files to see if any one of them, in particular, causes a crash? One by one perhaps? Or does the crash only occur when many (~15) are drag-n-dropped?

Thanks for the bug report!
