(Sorry I can't work on this myself. I was just planning on adding a description; I'm not really in a position to fix this new issue locally.)

why have you added me to the cc list for this ticket ?

[ryandesign (Ryan Carsten Schmidt)]

You added yourself to the Cc list for this ticket some time ago, but during spam cleanup it was necessary to delete that addition, so I re-added you manually.

[cjones051073 (Chris Jones)]

Ah right, thanks ! No idea why I did that now....
