Hi Clint,

At the beginning of May the .WORDLIST_VERSION meta-token was added to
bogofilter's wordlist.  At the moment it's sole use is determining the
prefix for subnet tokens, i.e. whether they should be url:12.34.56.78 or
ip:12.34.56.78.  More recently it was realized that .WORDLIST_VERSION
wasn't being set for newly created wordlists.  In older versions of
bogofilter, when it needed to read the wordlist and it didn't exist, the
db_open() routine would simply create the wordlist.  Now, ds_open() is
responsible for creating the wordlist (if necessary) and adding the
meta-token (if appropriate).  As Erwan David discovered, this is not yet
being done correctly.  Later today, I'll look at it in greater depth and
see what sort of solution I can create.

Regards,

David
