Package: src:python-zake
Version: 0.2.2-2
Severity: important

Dear maintainer:

I tried to build this package in buster but it failed:

--------------------------------------------------------------------------------

The build was made in one of my autobuilders with "dpkg-buildpackage -A".

The failure happens randomly, i.e. sometimes it fails, sometimes it does not,
so I don't have a "recipe" to reproduce it as such, but the "randomness"
is reproducible in my autobuilders (i.e. when I build it a lot of times,
there are always some failed builds).

I've put several failed build logs here for reference:

https://people.debian.org/~sanvila/build-logs/python-zake/

If you need a test machine to reproduce this, please contact me
privately and I could provide ssh access to a machine where it happens
(caveat: randomly and maybe with low probability).

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the BTS web page for this package.

Thanks.
