Crashes when encountering any file or directory that is not a project

[trevor@…]

The plugin crashes when encountering any file or directory that is not a project containing a proper VERSION file. The "Available Projects" section at the root url ignores these miscellaneous files and directories (such as extra-templates and scripts for creating new Trac instances).

Traceback (most recent call last):
