The 'c' keybind sometimes doesn't drop into insert mode

[Morgawr]

I tend to use the 'c' character a lot to delete + insert text in a single keystroke. Sometimes after I have been working for a while, I realize that hitting 'c'+something (like 'cw' or 'ct(' ) it will delete the contents but not drop me into insert mode.
I fear this might be related to bug #38 but I am not sure.

I can't reproduce this on osx 10.9. Please provide more info to make this reproducible.

I have the exact same issue on Arch Linux, LightTable 0.7.2, Vim 0.1.0. The bug doesn't seem to affect me on CodeMirror's vim demo, but as Morgawr said, it only arises after working for a while.

Any suggestions on debugging this? Is there some way to log all keypresses to a file, for example?
