(if you confirm that I'm going to update the original test file in the LilyPond git repository accordingly). The correct rendering of the second bar in wavy-line.xml is to output no trill at all, I guess, probably emitting a warning.
Anyway, xml2ly translates the MusicXML code to \startTrillSpan \stopTrillSpan (not counting the problem with the incorrectly inserted \barNumberCheck), which LilyPond doesn't like, since you cannot start and stop a span at the same time step.

Consider the MusicXML file in the attached archive and process it with

Here, a wavy line starts and ends at the same time step, but there is no
