This error is caused by an invalid file in /usr/lib/pkgconfig. The most likely cause is that after upgrading to libpng-1.5, you did not run the revdep-rebuild command that libpng printed in its post-install message. *** This bug has been marked as a duplicate of bug 383655 ***
My mistake, revdep-rebuild fixed the issue (but has also introduced new issues, already reported as bugs for upgrading to libpng 1.5 :D )
