Short description of error
Shortcut for Loop Cut and Slide cannot be saved after mapping with keys other than Ctrl R.
Exact steps for others to reproduce the error
Open User Preferences -> Input, then choose preset other than the default (say “Maya” for eg). then assign a new keymap for Loop Cut and Slide, save the configuration. Then restart Blender to see whether it was successfully assignd, or initialized.
