Nope. I haven't had a chance to deal with it. I can try to look this

For this to work we'd probably need to use cairo gradients for pdf

looked at doing it.

There is the ChangeLog file. But yes, I agree, using cvs is painful.

I think this might be fixed now.

I'd like to be able to help here, but I don't think you should hold up a
release waiting on it.
