[Pkg-bazaar-maint] Bug#848061: qbzr: FTBFS randomly (failing tests)

[Santiago Vila]

Package: src:qbzr
Version: 0.23.1-1
Severity: serious

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

It fails randomly. Sometimes it fails. Sometimes it does not.
If you try to reproduce it, please ensure that you try enough times.

I attach four different build logs.

Thanks.
