Hi Dan,
* Which version of PhpWiki, the nightly build or one of the releases?
* What actions before the error occurred?
* Which database is being used, MySQL or another one?
* If one of the SQL databases, are you using PEAR or ADODB as the 
backend? (If you didn't change this in index.php, the default is PEAR).

Email me the info so I check whether there a bug in the code. It could 
also be a record is corrupted in your database. Best to make a zipdump 
backup of all pages right away.

If you can't get a backup pagedump of all pages due to this assertion 
error, try temporarily deleting or commenting out that line 787 in 
lib/WikiDB.php:

    function getRevisionBefore($version) {
        $backend = &$this->_wikidb->_backend;
        $pagename = &$this->_pagename;

        $version = $this->_coerce_to_version($version);

        if ($version == 0)
            return false;
        $backend->lock();
        $previous = $backend->get_previous_version($pagename, $version);
        $revision = $this->getRevision($previous);
        $backend->unlock();
-       assert($revision);
+       //assert($revision);
        return $revision;
    }

Then delete the database and start a new one (or drop all the tables 
and recreate them with the appropriate schema file supplied in Phpwiki, 
same effect).

Let us know what happens.

Carsten
