[tahoe-dev] Weird WUI Error

Hey list,

I installed a new storage node the other day (which just happens to be
my introducer too), and I seem to have this problem where the WUI (on
:3456) keeps going to an "Internal Server Error" page every few hours. 
If I restart the process, then it's fine again, but it's back to the
error page when I check it a little while later.  I'm not sure what's
going on, because I have pretty much an identical storage installation
on another box that works perfectly fine.

Here's my twistd.log: http://paste.pocoo.org/show/321423/

And here are the details of my tahoe-lafs installation:

The crazy thing is that the reportedly missing file in twistd.log does
exist...

Not sure what's going on here.  Hopefully someone can shine some light
on the situation.  Thanks for your help
