Thank you for the bug report. Can I kindly ask you to create an official issue for this?
Go to <https://bugs.lttng.org/projects/babeltrace/issues/new>. I'd also like you to attach the offending CTF trace so that I can analyze it if it doesn't contain sensitive data and is somewhat small. If it's not possible, do: $ babeltrace2 -o ctf-metadata /mnt/ssd/work/skim/traces/kernel | grep -A10 '^clock {' and copy the output to the Redmine issue's description.
