After shutting down pimki and restarting again, accessing the home page of pimki causes a major error and no content
page can be displayed.  I'm running pimki 1.8.2 on WinXP with ruby 1.8

Error message:  undefined method `categories' for nil:NilClass

Hi Joe,

I think this may be the (occasional) corruption bug with
zlib/Madeleine. A short term workaround is to open the latest
.snapshot file in the storage directory in a non-zlib based zipper
(e.g. from 7-zip.org), extract the contents, and zip them again
in GZip format. Place the new zip as the latest .snapshot (by
squential number) into the storage directory and restart Pimki.

You'll be glad to know we're currently working on a reimplementation
of Pimki with will not be based on madeliene but on standard
ActiveRecord and SQLite3 (which is almost as easy to setup :).

Let me know if it solves the issue.

Cheers,
Assaph
