TracMercurial (0.12.0.27) conflict (hg 2.0) ?

[spinor]

While "tracd" seems to run without error, the website is not functional as soon as "tracext.hg.*" is set to "enabled" in trac.ini.

A typical error: Trac detected an internal error: TypeError: plain() takes exactly 1 argument (2 given)

(The above occurs for most (all?) buttons/links pressed on the website.)

Traceback obtained when pressing the "Login" button:

Looking at the traceback, this really is a duplicate of #10336, and was fixed in [10698], but we haven't made a release of the plugin since then (0.12.0.27 is at [10620]). In the meantime, please install the plugin from SVN directly.
