Ubuntu 14.04 64bits NVIDIA Titan Black
Short description of error
In graph editor or dopesheet, when a channel is selected , Ctrl I (assigned to anim.channels_select_all_toggle) is supposed to deselect it and select the unselected ones.
In practice, it only deselect current selection.
Exact steps for others to reproduce the error
In attached .blend, position mouse cursor over source region and press Ctrl I.
As expected, Y channel is deselected. But X and Z channels are still unselected, too.
