avoid this message :

PHP Warnings are not "serious" enough for maintainence releases, They do not prevent any functionality, and should not be enabled on a production website.

This part of the code is run a bunch of time (in fact each time a mysql query is executed).
So each time it is executed, PHP detects the error and runs the logging process (even to detect this error should not be punched).

I change milestone to 2.9.2 + dev-feedback for two reasons :

• patch is very simple.
• patch has a global impact on wp performances.

Jup, it's important to keep in mind that the @-operator is a hard hit on performance. Avoid if possible.

There are plenty of queries executed ... .

-1 The message in OP should never be displayed because it is suppressed by the error control operator. There is no bug here. I agree with dd32 it is not relevant to the 2.9 branch unless there is a reproducible bug.

+1 Now would be a good time to commit and close.
