What do you mean by 'strange' ?

If you are using the CVS tree, I just made a change to fix that bug. It
was a logic error that there was a || there instead of &&

It was:
if (!(isset($GLOBALS['sqlvalidator_error'])
      || !$GLOBALS['sqlvalidator_error'])) {
  // create new class instance
  $srv = new PMA_SQLValidator();

Now it is:
if (!(isset($GLOBALS['sqlvalidator_error'])
      && !$GLOBALS['sqlvalidator_error'])) {
  // create new class instance
  $srv = new PMA_SQLValidator();

Because the first case caused a complete evaluation on the globals on my
system, and spat out an error from that.
Notice: Undefined index: sqlvalidator_error in
/home/robbat2/cvs/phpMyAdmin/libraries/sqlvalidator.lib.php3 on line 67

This line was really deceptive, as it really says:
if NOT ( isset($GLOBALS['...']) AND NOT $GLOBALS['...'] )

I'm still not 100% that I have my logic correct their either.
