Description Stuart Anderson 2005-07-24 04:21:44 UTC

valgrind gives the following complain several times during start up. It looks 
like there may be a path where the pixel value is not being initialized.

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

Not sure exactly which commit fixed it, but no longer seeing this with pre-1.16.
