make sure you have an up to date babeltrace version. If the problem persists with an updated version, can you send me a link to your original "combined" trace files ? (a .tar.gz would be perfect). This use-case works fine here. Please note that babeltrace-log will simply take a text log and save each line into a CTF trace (as a string).
