Vim is installed at /usr/share/vim.
All snipMate\'s folders were added to this category in existing folders (after, autoload, plugin, snippets, etc.) accordingly.
<I solved this problem by removing the 'set paste' entry on .vimrc
I had a problem with snipMate, it wasn't working, so I came across with Issue 66 in their Issue Tracker:
source ~/.vim/after/plugin/snipMate.vim
In my case, I experienced the same thing. SnipMate autocomplete does not work. One of the reasons is the is used by other plugin. Typing :verbose imap <Tab>
will show you which plugin that utilizes the key and cause the conflict. You can either comment out the plugin in .vimrc or you can change it to use another key.
