Window doesn't open when launched from the Dock or Finder

[0xdd-co]

Steps to reproduce

1. Launch MacVim from the Dock or Applications folder
2. New window does not appear.
3. File -> New Window and File -> Clean Window does nothing.

I removed .vimrc, .gvimrc, .viminfo, and all plugins and the issue persists.

If MacVim is launched directly in terminal via /Applications/MacVim.app/Contents/bin/mvim, everything works as expected. Similar issue was raised in a Google Groups discussion.

Expected behaviour

A new window should appear when launching the app.
