I have a bookmark for a Git repo containing a directory with a npm package.json file. `npm install` in this dir creates/updates ~200k files in `node_modules` subdir.

My `~/.gitignore_global` contains (amongst others)

node_modules/
bin/ 

The repo `.gitignore` also contains

node_modules/

When I start SourceTree, the app works as expected. In the window for the above repo, Workspace > File status for "All files" doesn't show files that should be ignored.

If I delete the `node_modules` directory, SourceTree hangs, displaying the spinning "beachball" for ~2-3 minutes. Behaviour is similar when using `npm install` to populate the dir, or to make large updates to the dir.

This occurs even if the repo window isn't open but the repository browser window is open.

`git status` executes swiftly.

Expected behaviour: since `node_modules` is ignored, changes to files in this directory shouldn't cause noticeable effects to SourceTree.
