Tag in a project listed twice

[jakubgarfield]

A tag is listed twice in the project – firstly with the relative path and secondly with the Users/username/... prefix.

I simulated the issue with all other plugins disabled and running only with vim-bundler in my .vimrc. Any ideas what I might be doing wrong?

I've had the same issue, but I think the problem is in gem-ctags not in vim-bundler. I noticed that it is triggered by installing the rails gem, because it is just a dummy with dependencies and no code inside, so gem-ctags ends up with an empty list of paths and thus runs ctags without arguments here:
https://github.com/tpope/gem-ctags/blob/master/lib/rubygems/commands/ctags_command.rb#L27-L36

So what happens is that the current directory is indexed and the tag file is saved under the rails gem. Assuming that the current directory when installing the gem was your project and that you have an actual tags file inside the project you will get duplicates.

If that's the case a simple if paths.any? ought to do the trick.
