Saved in Krita 2.6 .kra file filter layer with color adjustment looses it's settings (curves reseted to default) when open in 2.8pre-alpha.

Versions: git master from 2013.07.13 and 2013.07.19

Try to talk to Boud about it on IRC.

Oh zut... That is a bad regression. Can you create a bug and attach a test file?

Ok, Boud, I working on it.
First, I found that in 2.6 format it's only 3 curves (no alpha), but in 2.8 is 4. (in *.filterconfig)

Ah! That's the alpha curve that got added.
