This happens if you don't pass the right directory to "lttv -t". You have to give it the one containing the metadata_* and ust_* files directly. However from your tarball, your metadata_0 and ust_0 files are in different subdirectories. Is this what you obtained from a single invocation of usttrace? If so then it means your different channels end up in separate traces, and this is definitely not normal behavior. If you put both ust_0 and metadata_0 files in the same directory, and open that directory with LTTv, what do you get? I couldn't open it from here, but I think it has to do with different endianness.
