[Python-apps-team] Bug#774424: trac-subcomponents: Trac query broken with this plugin enabled

[W. Martin Borgert]

Package: trac-subcomponents
Version: 1.2.0+hga86f0413121f-3
Severity: grave
Tags: patch, upstream

grave, because it makes the package in question mostly unusable

Trac queries don't work anymore, if this plugin is installed and enabled.
One gets a Python exception:
"UnicodeError: source returned bytes, but no encoding specified"

Problem description and patch here http://trac-hacks.org/ticket/11752 are OK:
