Comment 42 for bug 459523

Hi Barry,

Indeed, the problem was fixed upstream a long time ago. I don't take
any responsibility for making sure the individual distributions
properly merge the patches, so if you have issues with some
distribution you really need to take it up with the distro maintainer.

Cheers,

Devin
