Minimserver crash - fixed in Release 72

[Pastim]

I am helping to test a new feature in a Control Point. Whilst doing so I got the crash below. The CP is putting together a long list of tracks, in minimserver groups,to play random groups. The crash only seems to happen when the number of tracks is large.

It may well be that the CP is doing something wrong (this is very much Alpha testing), but any help or advice would be welcome.
