Bug#1016749: pytango: autopkgtest failure on armel

[Paul Gevers]

Source: pytango
Version: 9.3.4-2
Severity: serious
User: debian-ci at lists.debian.org
Usertags: fails-always

Dear maintainer(s),

You recently added an autopkgtest to your package pytango, great. 
However, it fails on armel. Currently this failure is blocking the 
migration to testing [1]. Can you please investigate the situation and 
fix it?

I copied some of the output at the bottom of this report.
