Hi,
gdk-pixbuf 2.42.11 has dropped support for several uncommon image formats. This is causing several applications to crash in Fedora rawhide [1][2]. (The change also got backported to F40 and F39, but I've reverted it there.)
Benjamin Gilbert has proposed reenabling the removed loaders [3], but this is not likely to be accepted upstream. So he's currently planning to package the removed loaders for Fedora in a separate package. You'll be able to depend on these if needed to avoid crashing, but please do so only if you really need to, since the goal of removing the extra loaders is to reduce attack surface. (Unfortunately gdk-pixbuf is a fairly risky dependency: many applications require it, but it's not very safe.) Most applications should use modern image formats instead.
Michael
