It gives you hints like "buffer position 28726". You can press "M-g c" and enter that number to jump to that location, which is a character location of the error.
I wrote a guide on how to use package.el to install your package and how to customize and extend your Emacs here: http://tuhdo.github.io/emacs-tutor3.html, if you want control of your configuration from scratch.
Probably if you do not have proper Elisp learning, you should use Prelude: https://github.com/bbatsov/prelude. Everything is configured for you and packages are downloaded automatically. This is the easy way. Put your personal configuration code in ~/.emacs.d/personal/. You can also enable additional modules based on your need in ~/.emacs.d/sample/prelude-modules.el by toggling off comments: https://github.com/bbatsov/prelude/blob/master/sample/prelud....
I haven't tried loading from a different location, but you should try in your ~/.emacs.d first. Are you sure your packages are installed in Dropbox folder? I think it is installed in ~/.emacs.d. You should use a VCS like Git to store your configuration in the same .emacs.d directory.
Finally, to make sure it is because Magit, you should uninstall it to see if your Emacs loads properly. In my Windows machine, it loads perfectly fine with more than 130 packages.
Actually I've used emacs since 2003 or so... but still.
Removing magit from ~/.emacs.d/elpa and reinstalling seems to have solved it. I'll check prelude.
