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. --8<---------------cut here---------------start------------->8--- Source file `/Users/schmitta/.emacs.d/org/emacs/site-lisp/org/ob.el' newer than byte-compiled file Source file `/Users/schmitta/.emacs.d/org/emacs/site-lisp/org/ob-exp.el' newer than byte-compiled file Source file `/Users/schmitta/.emacs.d/org/emacs/site-lisp/org/ob-lob.el' newer than byte-compiled file Loading /Users/schmitta/.emacs.d/custom.el (source)...

Wrote /Users/schmitta/.emacs.d/recentf --8<---------------cut here---------------end--------------->8--- 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?
