[TYPO3-dev] error with the svn version of TYPO3

[Gideon So]

Hi,

	I am using the svn version of TYPO3. Everything works fine but one
thing. When I click to edit a content element the frame become blank and
the web server  log shows this line:

PHP Warning:  mysql_fetch_row(): supplied argument is not a valid MySQL
result resource in
/path/to/typo3_src/typo3_src-svn/t3lib/class.t3lib_db.php on line 819.
Can anyone give me some clues??

Gideon
