I can confirm this issue (I think) with 5.4 and 5.4.357.

I spent some time trying to reproduce with Session templates but after a bit of head scratching I can reproduce a similar (maybe the same) issue:

1. Add a a-comp plugin to an existing track
2. Select the track in Mixer or Editor
3. Select Track -> Duplicate Track/Busses MenuItem and click OK

At that point it brings up an dialog with the error "1 or more tracks/busses could not be duplicated"

and in the log window the error:

[ERROR]: AlsaBackend::register_port: Port already exists: (ardour:Sidechain 2/audio_in 1)
[ERROR]: unable to create port: failed constructor

Is this what you are doing in your "Steps to reproduce" above?
