A package (gnomeicu) I have tried to build recently is checking for gdk-pixbuf version >= 0.9.0, and thus failing the configure step. Is it possible to upgrade to 0.9.x without breaking stuff?
I believe most apps we currently use will still work - we are currently in the process of building GNOME 1.4 to push out to users (which includes 0.9x) you may either wait and let us test or be brave and try it out.
If you push something into Raw Hide I'll test it ASAP, or at least as soon as it hits a mirror nearby :o)
still building :)
