Ok, I've now also had time to look at this. I don't think the breakage
is that bad. All you really need to do is teach the parser about CFs.
Here's a suggestion for a patch. I'm not quite sure if I hit the
preferred way to test for a custom field, but it seems to work for me.

Let me know what you think and whether I should file a bug report.
