[Typo3] invalid result class.t3lib_db.php on line 702

[Scott Ott [ScrappleFace]]

In the BE, I'm still getting this error in the right pane:
*
Warning*: mysql_fetch_row(): supplied argument is not a valid MySQL 
result resource in */PATH_TO/typo3/t3lib/class.t3lib_db.php* on line *702

*Everything seems to be working, but that message still appears. How can 
I repair this?

BTW, I got rid of the FE display of a similar message in the Calendar 
extension by deleting the extension, which I noticed was still in Beta. 
I'm hoping we get a stable calendar extension soon. That would satisfy 
all our needs.
