TracCrystalXTheme not working in 1.4.1

[anonymous]

Tried TracCrystalXTheme in Trac 1.4.1. But as soon as it is enabled in the trac.ini, it throws error as shown in the attached snap-shot.

I get this error too.

Unfortunately, putting the Traceback in a jpeg hides the error detail from search engines.

For the record, mine looks like this:

The theme will need to be ported from Genshi to Jinja2 to work with Trac 1.4.

[Ryan J Ollos]

Note there is no 1.4 tag on the project page since this plugin is not compatible with Trac 1.4.

Was ported or not? https://trac-hacks.org/ticket/14059

[Ryan J Ollos]

Has not been ported.

Won't be unless someone takes an interest in it because the original maintainer is no longer around.

Any other working example template like main trac.edgewall.org to test and modify ?
