I have the same problem with Twitter Bootstrap, Rails and simple_form. A solution could be:

.form-inline .controls, 
.form-inline .control-group { display:inline; }

@martinpetrov seems to have nailed it—reset the display and nuke any other CSS properties that come with the default .control-group (should just be margin) and you should be okay.
