--- Short description of error ---
If you use the 'remove gaps' function [backspace] on a clip with a keyframe,
I.E: opacity, the clip moves to close the gap but the keyframes stay behind.

--- Steps for others to reproduce the error (preferably based on attached .blend file) ---
Open attached blender_2.67.1_vse_bug_01.blend file. In the sequencer there are two
clips. The second at frame 50 has a keyframed opacity curve from 0% at frame 50
to 100% at frame 60. If you remove the gap [backspace] at frame 25 the clip moves
from frame 50 to 25 like it's supposed to do. However the first keyframe will remain
at frame 50.
