Hi,Simen: This error caused by ‘end-of-file’ from 6b6637 at point (195,6). When I remove ‘end-of-file’, it’s works. 194 (define-error 'json-end-of-file "End of file while parsing JSON" 'json-error) -- Junqi At 2015-10-17 21:25:33, “Simen Heggestøyl” simenheg@gmail.com wrote: Sorry, but I'm unable to tell what's wrong from the provided information. Since Emacs starts fine from 'emacs -Q', you could try to track down which part of your initialization file is causing the error. Either way, if you've found that the error stems from commit 6aa04a5, I think that it deserves it's own bug ticket instead of discussing it here, since it's unrelated to bug #21488. When you report it, I think it would be good to include a backtrace to make it easier to track down the cause of the error. -- Simen
