This seems to be caused by an error in Swift (based on investigating 
with Jonathan off-list).

The bug is that if an app returns an array of files, then any non-array 
returns from the app are not getting handled correctly.
It seems to be a problem in the array-collecting code in the Swift 
app-launching wrapper, which may be loosing its directory context after 
returning from the collection function.

No, not at the moment. Some variations of this capability have been 
discussed, though. It seems to me to be a useful addition to implement.
