Hi Maximiliano,

Thanks for your report --

I had a quick look at the above link: to me it seems that the build
fails not due to broken metadata directories, but rather due to

  FAIL: test_all_parametred (tests.test_libmat2.TestCleaning.test_all_parametred)
  AssertionError: False is not true : got a different value (720000) than excepted [...]

which looks similar to

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=993209
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1021732
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1148580
  ...

The autopkgtest via ci.d.n is failing since quite some time as well.

Does this make sense?

Cheers,
Georg
