Comment 2 Alexander Bergmann 2022-04-19 11:02:22 UTC

There is a proposed fix in comment 1 from the upstream bug report.

https://sourceforge.net/p/podofo/tickets/75/

This could be relevant for our versions, but in the meantime it got marked as obsolete as version "r2035 doesn't dereference the NULL pointer" anymore.

Please check if the proposed comment 1 patch would work for us and submit for:

SUSE:SLE-12:Update
