[Python-modules-team] Bug#890479: pytz can't find any time zones

[Evgeny Kapun]

Package: python3-tz
Version: 2018.3-1
Severity: grave

After upgrade to version 2018.3-1:

     >>> import pytz
     >>> pytz.all_timezones
     []

This is caused by this line in /usr/lib/python3/dist-packages/pytz/__init__.py:

         filename = os.path.join('usr','share'
                                 'zoneinfo', *name_parts)

So, instead of looking at /usr/share/zoneinfo/$time_zone_name, it is looking at (relative path) usr/sharezoneinfo/$time_zone_name (note the lack of comma after 'share', which leads 'share' and 'zoneinfo' to be merged into a single string literal). This code is horribly broken, but it worked because it fell back to using time zone files bundled with the package. Now that these files are not included anymore (see bug #884079), this package doesn't work!
