Suppressing errors in `activities-mode-timer` about activities.el

[karthink]

Just updated, it appears to be fixed. Thank you!

Hi Karthik,

Believe me, I have encountered this myself, usually at the most inconvenient time, so I forgot to file an issue about it.

I thought that the new activities-anti-save-predicates option would solve this:

activities.el/activities.el

Lines 277 to 285 in 6ef5924

	(defcustom activities-anti-save-predicates
	'(active-minibuffer-window activities--backtrace-visible-p)
	"Predicates which prevent an activity's state from being saved.
	Each predicate is called without arguments, with the activity to
	be saved having been activated. If any predicate returns
	non-nil, the activity's state is not saved."
	:type '(set (function-item active-minibuffer-window)
	(function-item activities--backtrace-visible-p)
	(function :tag "Other predicate")))

It calls this function:

activities.el/activities.el

Lines 734 to 740 in 6ef5924

	(defun activities--backtrace-visible-p ()
	"Return non-nil if a visible window is in `backtrace-mode'."
	(catch :found
	(walk-windows (lambda (window)
	(with-selected-window window
	(when (derived-mode-p 'backtrace-mode)
	(throw :found t)))))))

Which should prevent it from trying to save an activity if a backtrace is visible.

Since adding that, I haven't seen the problem again. Are you sure you're using the latest version?

Well, it just happened to me again, so now I understand what you meant. :) I think the fix I just pushed should solve it. Please let me know if it happens again.
