Package: trac
Version: 0.12.2-1~bpo60+1
Severity: normal
Tags: patch
trac from backports has incompatibility with genshi version that causes
error when trying to browse some old tickets.
Call to genshi.core's escape method with two arguments (second being
False) all fail, such as here:
return resolver(self, ns, target, escape(label, False),
TypeError: unicode() argument 2 must be string, not bool
By modifying call to use keyword argument for second parameter, it
works. Patch below.
