The following report raises an error when view it from raco dbg (I'm not sure how best to test it without having a dbg server running, but I observed this when double-clicking the report in an existing instance):

Thanks for the report! I've pushed a fix, although the profile itself is not very helpful. Usually, to get good profiles you have to:

1. Remove any app-specific compiled .zos
2. Turn on errortrace for the app (eg. racket -l errortrace -t main.rkt)
3. Toggle Errortrace? in the debugger before recording
