Jill,
That would be one of my diagnostic messages in Media Gallery. Now, I should not have let that slip out into the production release, my apologies. It is nothing to worry about, just an informational message in the albumedit.php file.
If you want to remove it, edit
maint/albumedit.php and around line 703 you should see the COM_errorLog("WE are....), just delete that line.
Thanks!
Mark
