Yes, it works fine in my tests. I was never able to reproduce your issue. Even on a clean install with CB and CB AntiSpam only. Reviewing your error further it seams the culprit is the below.
Code:
#3 /var/www/html/plugins/system/joomcrmform/joomcrmform.php(31): JEventDispatcher->trigger('oninit', Array)
For whatever reason your 3rd party plugin Joom CRM Form is running the onInit event for every plugin. This includes Captcha plugins. It's doing this on onBeforeRender, which is too early to be forcing CB to load. This seams like an incorrect way of doing this and recommend contacting the developer or seeing if that plugin has some sort of exclusion functionality.
