Failure on loading some .spine/.outline files
Some tracks in Choreography files cause a bug in DecoratedLarva
with:
ArgumentError: collection must be non-empty
The path
attribute is supposedly empty, while the files actually define many time steps.
Steps to reproduce: Download these sample files, unpack them and open either the .spine or .outline file with larvaeditor.
Proposal: Catch the errors and skip the problematic tracks.
A same problem may occur at the backend level. We'll see.
EDIT:
Exact same error in the backend, although it's Python code: ValueError: need at least one array to stack
