[SOLVED] tagValue Artist.merge does not work with certain tagUpdate file?

[simoncn]

If you can see the conductor in the Conductor index and this Conductor index entry contains all tracks that should have this conductor, this means tagUpdate has added the Conductor correctly.

I am not aware of any bugs in tagValue. To investigate this further, I would need a specific example of a Conductor tag that is not present when browsing the All Artists container.
