[Python-modules-team] Bug#750233: python-networkx: FTBFS - test fail, order not deterministic?

[Michael Tautschnig]

Package: python-networkx
Version: 1.8.1-1
Severity: serious
Usertags: goto-cc

During a rebuild of all Debian packages in a clean sid chroot (using cowbuilder
and pbuilder) the build failed with the following error.

[...]

Further failing tests follow - the full build log is attached. It seems the
order of those lists isn't as deterministic as should be.

Best,
Michael
