dash is black after login

[Andreas E.]

After every boot (or logout – login), the dash is (almost opaque) black. I need to choose a different wallpaper (and then the original again) to make the dash appear colored.

This happens since the first day of 13.10. This bug appears to be very similar to bug #1017164, but it didn't occur to me in 12.10 and for me the launcher and panel are perfectly colored and transparent.
