There seems to be an issue with serialization/data-saving. I'm getting a LOT of warning in my error logs saying:

[19-Jun-2007 11:31:55] PHP Warning: unserialize() [function.unserialize]: Node no longer exists in C:\webs\video_embed\devel\includes\bootstrap.inc on line 342

Sometimes i get the reverse with "serialize". The only way i have found to stop it is to delete my entire variables table (delete from variable). i don't know what gives. i've run update.php forcing it to start with update 1 a couple times.
