Enabling tracdownloader.web_ui.downloadermodule causes LookupError: unknown encoding:

[duncan-bugs@…]

Just installed the Trac, genshi, etc from svn (using gentoo Python-2.4) and was hit by a bug when installing the TracDownload. Anyway you'll understand it as it's only a one liner.

Sorry but I should raise bug reports for the other problems that I've encountered along the upgrade path from 0.10.4. but I'm lazy ;-)

• eggs are being called -r0 instead of -rXXX (possibly Python-2.4 problem) renaming the files and hacking easy-install.pth sorted this out.
• SetEnv PYTHON_EGG_CACHE in apache2 config doesn't work, easy_install -Z . sorted this out.

Thanks I really like trac.

Please report this to the maintainer of the corresponding plugin (​TH:TracDownloaderPlugin). At the same occasion, tell him to use req.href.downloader() instead of self.env.href.downloader().

I've added a note about this issue in TracDev/ApiChanges/0.11@36.
