In my case mu4e compose mode, everytime I got the error below:
Error running timer `org-element--cache-sync': (wrong-type-argument hash-table-p nil)
This simptom is already subscribed as bug, but unresolved. https://lists.gnu.org/archive/html/emacs-orgmode/2015-08/msg00947.html
It seems that
(setq initial-major-mode 'org-mode) makes this happen.
Are there any good way to get rid of this timer error?
