Source: python-tblib
Version: 1.4.0-1
Severity: serious
Tags: ftbfs

Dear Maintainer,

python-tblib currently fails to build from source with the following 
error message:

==================================== ERRORS 
====================================
___ ERROR collecting

Hint: make sure your test modules/packages have valid Python names.

I got the same error message when attempting to build it on my Sid 
system.
