TagFormat error

[jolivetj]

Hi Simon,
I have recently upgraded to the full Minimserver 2 package.
I now get this error message after rescanning:

Browse request from 192.168.0.17: 0$=Conductor$16980 isn't a valid object

My TagFormat string is the following:
Artist.displayFormat={$composer$artist$orchestra$conductor^^^ / }

How can I fix this?

Thank you
