For reasons I don't have time to dig into and figure out, some builds of nautilus in Fedora have produced a libcrc32.so, while others have produced a libcrc32.a. And then things like librados2.so and others are linked with it.
When libcrc32.so is built, it's not included in the RPM and a dependency on, e.g. the librados2 RPM, is derived, with the result that an install/update fails because there is nothing that provides libcrc32.so.
Forcing libcrc32 to be a STATIC library appears to work, e.g. with the attached patch.
