 Is early rebuilding of gdk-pixbuf still needed now that fixed version
 will be stabilized before libpng15?

The blockers that will force gdk-pixbuf to rebuilt first will just
ensure there are no -lpng14 or -lpng15 entries in gdk-pixbuf-2.0.pc that
would break apps compile-time.

The rebuilding of gdk-pixbuf and cairo is still necessary early, because
apps using gdk-pixbuf to handle .png at buildtime AND runtime (mostly
gnome apps) will fail with message .png: File type is not supported
(Maybe not with this exact wording, but close to it.) that is an result
of condition where eg. cairo is built against png14 but gdk-pixbuf with
png15 or otherway around -- conflict

OK, thanks a lot for the explanation :)

 identify those files with following one-liner: ... # find /usr/
 -name '*.la' -exec grep png14 {} +
What happens once you identify the broken .la files? Should people
delete these .la files? Should they just rebuild the package? Should
they run lafilefixer? I think you need to add some bits here on how to
deal with the remaining .la files ;)

I think it's better to put all knowledge from forum post inside:
1.  --keep-going option for revdep-rebuild.
2. better find:
find /usr -name *.la -o -name *.pc -o -name *-config -exec grep -H
png14 {} \;
or even better to provide one-liner for user's convenience.

This is going to take less grep calls, and it is easier to type too.
