From 0823791d1793dc28b0c374dd332e9d1b24acfee1 Mon Sep 17 00:00:00 2001 From: zeripath Date: Wed, 30 Jan 2019 22:17:43 +0000 Subject: [PATCH] Recover panic in orgmode.Render if bad orgfile (#4982) (#5903) This PR protects against the panic referred to in chaseadmsio/goorgeous#82 by recovering from the panic and just returning the raw bytes if there is an error.
