Introduce a cut-down version of my .ini parser; this one doesn't do anything special with indents, and just builds a simple dict on parse. It does introduce the same error handling (other than that for indenting), so some previously working (but highly dubious) configs might break.

Hook up a [keybindings] section, to override the default ones now in config.py; teach TerminatorConfig to merge configured keybindings from available sources; gconf support shouldn't be far away.
