[Cin] Video Transitions not locking into track?

[Stefan de Konink]

I am using a recent git version of Cinelerra, and I notice that I cannot 
drop a video transition between two pasted clips anymore. So I do see the 
white square as placement, but the icon after it does not follow. Neither 
is the transition visually applied between the two clips. (I have also seen 
the case where the icon isn't there, but the transition happens, but not 
today.)
