1) Put a clip on a track, make an edit with a crossfade (or an overlapping clip).
2) Copy some audio into the clipboard.
3) Make a selection over the clip downstream from the edit, and shorter than the amount that you have in the clipboard.
4) Paste special repeat to fill selection (opt-cmd-v).
5) Boom! Graphical error, AAE error 9480, playback does not include the edit, waveforms are blank.
Totally repeatable. Thanks in advance Avid for getting this!
