Here you are :

-------------cut-here------------
Debugger entered--Lisp error: (void-variable overlays)
  htmlize-sorted-overlays-at(1)
  htmlize-faces-at-point()
  htmlize-buffer-1()
  htmlize-region(1 58)
  org-html-htmlize-region-for-paste(1 58)
  org-html-fontify-code("int main() {\n    printf(\"hello world\\n\");\n
return 0;\n}" "c")
  org-html-do-format-code("int main() {\n    printf(\"hello
world\\n\");\n    return 0;\n}" "c" nil t nil)
.....
-------------cut-here------------

It is htmlize-faces-at-point(), and only when the exported org-buffer
contains a snippet of code. Otherwise, the export process works fine.
