[Bug 1582992] Re: broken apport hook: TypeError: Can't convert 'bytes' object to str implicitly

[Brian Murray]

Here's a test case that should be easily reproducible using the data in
this bug.  Use download-crash from the bugpatterns bzr branch to create
a crash file for this report e.g. ./download-crash 1582992. Then run the
following in python:

 $ python3          
Python 3.5.2+ (default, Sep 22 2016, 12:18:14) 
[GCC 6.2.0 20160927] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import apport
>>> report = apport.Report()
>>> f = open('report-1582992.crash', 'rb')
>>> report.load(f)
>>> from apport import hookutils
>>> hookutils.attach_mac_events(report, ['/usr/lib/libvirt/virt-aa-helper', '/usr/bin/libvirtd', 'libvirt-.*'])

This did not crash for me on yakkety.

  # ubuntu-bug libvirt-bin

    from gi.repository import GLib, Wnck, GdkX11, Gdk

  During handling of the above exception, another exception occurred:

  Don't worry about the Wnck thing, that's bug 1580412.
