Server error on '/raw' prefix test site

Hey there, just testing out the '/raw' test site mentioned in #962: http://127.0.0.1:43110/raw/1AsRLpuRxr3pb9p3TKoMXPSWHzh6i7fMGi/en.tar.gz/index.html

I get the following error when attempting to load it:

Err: AttributeError: 'NoneType' object has no attribute 'needFile' in UiServer.py line 93 > UiRequest.py line 104 > UiRequestPlugin.py line 22 > TranslateSitePlugin.py line 25 > FilePackPlugin.py line 52
