Thanks for the report, I've attached a patch that fixes this problem (in
both `org-display-inline-images' and `org-preview-latex-fragment').
However I don't know if it is the right approach or if I should try to
narrow this to lower-level functions.
I know that `clear-image-cache' raise this error but I haven't tried to
see if it the only one. Should I try to look more at it and add a
`org-clear-image-cache' which will check if a graphic display is
available or is the current solution fine?
Regards,

Subject: [PATCH] lisp/org.el: Do not inline images when no graphic display is
available
* lisp/org.el (org-preview-latex-fragment)
(org-display-inline-images): Detect whether a graphic display is
available before inlining images to prevent an error.
Thanks to Rick Frankel for the report and the solution.
