bismillah. when i tried to use the gmail->todoist bookmark i got the
message "Gmail email not loaded."
no window opened, and the task was not added.
the error occurred while using the default version of Gmail:
http://mail.google.com/mail/?ui=2
the bug disappeared when i switched to the older version of Gmail:
http://mail.google.com/mail/?ui=1
and when i switched back to the "newer version" the bug did not
reappear.
so (1) it was a temporary problem, and (2) it was pretty easy to fix,
but the bug did not disappear until i switched versions -- just
reloading Gmail and the e-mail I wanted to tag was not sufficient.
