You need to upgrade to syslog-ng 1.5.12 and libol 0.3.1
and apply this (little) fix[0].

Now my syslog-ng doesn't crash anymore.

Hi,

The patch below hopefully fixes the "Type Error" problems reported in
1.5.12. I'd appreciate feedback whether it really fixes the bug.
(if it does, expect a new version shortly)

Thanks for the cooperation for those who helped me to track this issue.
