[O] how can I debug an async export error?

[Alan Schmitt]

Hello,

I have a file that exports well synchronously, but that fails when
exporting asynchronously. I set the `org-export-async-debug' to t but
the Org Export Process buffer that is left behind in not very useful.

The error seems to be the “Invalid color” near the end, but I have no
idea where it comes from.

Is it possible to ask org-async-export to leave a backtrace in this
buffer when it fails?

Thanks,

Alan
