Dependency remains on clips that were loaded with a subsequently deleted matrix view.

I used the matrix view to audition some clips and then I deleted it and the track it was attached to.  Unfortunately, the project reports those clips missing when I load it.
 
Anyone know of a good way to delete them?  I've already tried bringing back the matrix view with a track of the same name and it didn't show the orphaned clips.
