[Reproducible-builds] Bug#833738: python-popcon: assumes all-popcon-results.txt.gz is UTF-8

[Chris Lamb]

Source: python-popcon
Version: 1.3
Severity: serious
Tags: patch

Hi,

Since (at least) 07-Aug-2016 14:04, the all-popcon-results.txt.gz file
contains an invalid line:

    Package: libfyba0-dbg                       0     2     0     0
--> Package: libf erdp-ommon                    0     0     0     1
    Package: libg++2.8.1.3-dbg                  0     0     0     1

That's (currently) line 54869. The "space" on the second line is actually
a 0xa0 character. This is making the package unusable.

$ python3

    data = _fetch()
  File "/usr/lib/python3/dist-packages/popcon.py", line 108, in _fetch
    txt = _decompress(txt)
  File "/usr/lib/python3/dist-packages/popcon.py", line 134, in _decompress
    data = data.decode()
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 3574857: invalid start byte

Patch attached. NB. the comment in the lookup section.
