           Version: 1.3.3
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR

Hey guys:

steps to reproduce:

(1) open document
(2) strg+shift+p
(3) esc
(4) strg+shift+p
=> crash

Happens on all pdfs I tested (around 20 different sources)
I can send PDFs for reproduction if someone has a problem with it.
I have also strace logs (the end of one is included at the end) and can make
additional logs if it is helpful.

strace end:
