Due to no *.css files present in htdocs, the directory is not included into the egg.

The situation in the summary resulted in an interesting error at our Trac instance, when used together with other plugins, particularly, the TimingAndEstimationPlugin:

14:55:33 Trac[main] ERROR: Internal Server Error:

    zip_stat = self.zipinfo[zip_path]

Notice the last line.

I suspect there was a time when there were actual css files there. The extremely trivial and ugly fix is to simply create an empty dummy.css file under htdocs/css, and all is well. Specifying a directory for "package_data" in setup.py failed, and so did htdocs/*. Did not try further.

Patch for #11223 against tracticketdepgraphplugin/0.11@13335​

[Jun Omae]

In this case, I think that DepGraphModule.get_htdocs_dirs() should return [] because the plugin provides no css files. Please try ticket11223-tracticketdepgraphplugin-r13335.diff​.

Don't include empty htdocs directory. Fixes #11223.
