Package: python-pygal Version: 1.7.0-0-g41186be+1 Severity: grave Justification: renders package unusable
Dear Maintainer, there is a bug in pygal that makes it crash even when running the first example in its documentation, a bug which seems to have been fixed about a month ago in version 2.0.11 of pygal; here is the relevant issue https://github.com/Kozea/pygal/issues/282 This bugs makes it impossible to generate any SVG (BTW, in this package's description, "Python svg graph plotting library", "svg" would be better written in uppercase). This is the example from http://www.pygal.org/en/latest/documentation/types/line.html import pygal line_chart = pygal.Line() line_chart.title = 'Browser usage evolution (in %)' line_chart.x_labels = map(str, range(2002, 2013)) line_chart.add('Firefox', [None, None, 0, 16.6, 25, 31, 36.4, 45.5, 46.3, 42.8, 37.1]) line_chart.add('Chrome', [None, None, None, None, None, None, 0, 3.9, 10.8, 23.8, 35.3]) line_chart.add('IE', [85.8, 84.6, 84.7, 74.5, 66, 58.6, 54.7, 44.8, 36.2, 26.6, 20.1]) line_chart.add('Others', [14.2, 15.4, 15.3, 8.9, 9, 10.4, 8.9, 5.8, 6.7, 6.8, 7.5]) line_chart.render() and this is the traceback when running it interactively: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.7/dist-packages/pygal/ghost.py", line 122, in render .make_instance(overrides=kwargs) File "/usr/lib/python2.7/dist-packages/pygal/ghost.py", line 116, in make_instance self.xml_filters) File "/usr/lib/python2.7/dist-packages/pygal/graph/line.py", line 33, in __init__ super(Line, self).__init__(*args, **kwargs) File "/usr/lib/python2.7/dist-packages/pygal/graph/base.py", line 47, in __init__ self.svg = Svg(self) File "/usr/lib/python2.7/dist-packages/pygal/svg.py", line 50, in __init__ u('xml'), u("version='1.0' encoding='utf-8'"))] File "src/lxml/lxml.etree.pyx", line 3039, in lxml.etree.ProcessingInstruction (src/lxml/lxml.etree.c:81073) ValueError: Invalid PI name 'xml' -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Kernel: Linux 4.2.0-1-686-pae (SMP w/2 CPU cores) Locale: LANG=it_IT.UTF-8, LC_CTYPE=it_IT.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages python-pygal depends on: pn python:any <none> python-pygal recommends no packages. python-pygal suggests no packages. -- no debconf information
