TimelineUserFilterPlugin causes error "not all arguments converted during string formatting"

[Jonathan Turkanis]

After copying TimelineUserFilter.py to my plugins directory, each Trac page (not just the timeline) gives the following:

Internal Error

TracError: TypeError: not all arguments converted during string formatting

It is generally recommended that you provide some details about your system, staring with the System Information on the About page.

I had forgot that I submitted this ticket. It should be closed; I'll let you decide the resolution.

The problem was caused by the file ownership and permissions that result when I downloaded the plugin to a Windows machine and then scp'd it to a Linux server. Explicitly setting ownership and permissions to correct values fixes the problem.
