And, always FTR, this was the `bt' of the `zathura.core' (on a Dec
4 NetBSD/amd64 8.99.8 machine, with a mostly pkgsrc-current set of
packages as today):

% gdb -core zathura.core `which zathura`
Reading symbols from /usr/pkg/bin/zathura...(no debugging symbols found)...done.
[New process 1]
[New process 4]
[New process 3]
[New process 2]
Core was generated by `zathura'.

Please note though that after rebuilding cairo I can no longer reproduce
that!
