Installing Sublimerge Pro (in ~/.sublimious) fatally borks with sublimious

[bedge]

Tried it twice form a clean install.
First time I added Sublimerge Pro after sublimious was setup with a few extras, and I lost the 'space' menu keybinding.
Did a clean config reset.
Tried again adding Sublimerge Pro as the first add-on. It worked once, then, after restarting the sublimious space menu keybinding was gone.
In each case, after this happens, editing the ~/.sublimious file and restarting sublime does nothing.
Had to purge ~/Library/Application Support/Sublime Text 3 and start over each time.

Can't define 'borks' an more than what I experienced. I'm a noob sublime user so I don't know what other specific info to post.
In any case, it's easily repeatable.

May not be specific to the the Sublimerge Pro plugin.
Kept losing VIM-specific behavior after some time.
The "spc - ?" keybinding is the most recognizable thing to go.
The only consistent thing is that it doesn't happen until I make some manual change to ~/.sublimious.

This was enough to trigger the problem:

%> diff  ~/.sublimious ~/.sublimious.orig
42,43c42,43
<     # "shortcut_overlay_timeout": 1
<     # "show_shortcut_overlay": True
---
>     "shortcut_overlay_timeout": 1
>     "show_shortcut_overlay": True
53c53
<     # "line_numbers": False,
---
>     "line_numbers": True
55c55
<     # "word_wrap": True,
---
>     "word_wrap": True,
60c60
<     # "trim_trailing_white_space_on_save": True,
---
>     "trim_trailing_white_space_on_save": True,

Each time I have to "reset" by deleting ~/.sublimious, restarting, then set:
nuke_everything = True
restart again, etc.
