If iTerm2 is open, :Gpush on Macvim opens iTerm tab, then hangs

[jasonschock]

Using a vanilla install Macvim (build 73) via homebrew. Only plugins installed are pathogen, vim-dispatch, and vim-fugitive.

• Working within a git repo, with a file open, run :GPush
• IF I have iTerm2 open, a new tab opens.
  • It is blank.
  • Focus remains in Macvim.
  • Nothing happens in the iTerm tab, just seems to hang.
• In Macvim, the command line shows !git push (iterm/?)
• No git push actually happens.
• IF I have iTerm closed, the command works as expected.
• The command works as expected from vim running in a terminal.

The culprit seems to be :Make (https://github.com/tpope/vim-fugitive/blob/master/plugin/fugitive.vim#L1577), which is a vim-dispatch thing, where there seems to be some iTerm2 issues anyway.

I have a similar issue.

:Make command works well when executed from MacVim in iTerm. However, when executed from MacVim GUI, it opens an blank iTerm tab and hangs there.

I can confirm it works for me with iTerm2 and MacVim. Digging in will involve looking at the AppleScript in autoload/dispatch/iterm.vim. You can also work around it by removing iterm from g:dispatch_handlers.
