+1. Seems to happen when I attempt to move a pane too far to the left or right (as in, I have two panes open, focus in the left, and hit 'move tab to the right' multiple times in quick succession).

+1. I'm getting this error while using the key combination "Command + Control + Shift + Arrow Key" (Any arrow direction). I can't get any tabs to split into a new pane using that key combination, it just errors out for me. It will still split into a pane when right clicking on the tab and selecting the split option though..

Also I can still use the "Command + Option + - or =" for resizing -- providing they're already in a pane of course.
