Fix nullptr access on pkpass parsing failures

Comment 4 Volker Krause 2020-10-29 07:51:21 UTC 
As a workaround until you get the fix in 20.08.3 you can meanwhile just delete the file <LIBDIR>/plugins/messageviewer/bodypartformatter/messageviewer_bodypartformatter_pkpass.so (exact location depends on the distribution) to access view the affected email again.
