I tried and cannot reproduce this (also using a stereo region with silence on the left track).

Could you zip + attach the session?

Either this is specific for this session (e.g. the guitar sound and/or region boundary) or it has meanwhile been fixed (I checked with 5.4-472, the DSP library has been updated since 5.4.0).

I try to pitch shift the guitar and it never works.

I see, in this case you're stretching or pitch-shifting a region that has previously been time stretched.

In that case Ardour goes back to the original source (to reduce artifacts) but the original source is no longer available (at least it's not included in the .zip)

I suppose Ardour should print a warning and use the current (already processed) region in this case.
