Original GitHub issue: https://github.com/netblue30/firejail/issues/666

when you run tar with the new tar.profile, tar won't extract any file if --trace is given.
This might be an easy reproducer to debug this issue,
may be #561 is related to this.

plain tar archives seem fine, the trouble starts when a compressor like bzip2 is used (=forked).

hmm, during my testing --tracelog was broken but now it works.

--trace probably messes up the stdout <-> stdin pipe tar uses for the compressor subprocesses.
