After some time using conkeror, URL completion stops working. However, completion for M-x still works.
Not sure how to reproduce this yet.

After some point, as I type a URL, the following error message gets printed:

Error: 
chrome://conkeror/content/utils.js:338
abort()@chrome://conkeror/content/utils.js:338
(true,true)@chrome://conkeror/content/minibuffer-read.js:273
(0)@chrome://conkeror/content/minibuffer-read.js:234

Trying to autocomplete (TAB) prints this error message to the console:

Error:
